California Astrophotographer Wins American Astronomical Society (AAS) Chambliss Amateur Achievement Award

(the Sky & Telescope Press Release 2011-01-18)

January 18, 2011

The American Astronomical Society (AAS) is honored to announce that R. Jay GaBany, a product manager for Inter net-based companies from San Jose, California, is the 2011 winner of the Society’s Chambliss Amateur Achievement Award. The award is given annually to an amateur astronomer from North America who makes outstanding contributions to scientific research.

Using a 20-inch telescope at the remote Black Bird Observatory in New Mexico, GaBany has been one of the world’s leading amateur astrophotographers for the past decade. But his contributions go far beyond just taking pretty pictures. In recent years, GaBany has devoted hundreds of hours to work with a team of astronomers led by David Martinez-Delgado of the Max Planck Institute for Astronomy in Germany to take deep CCD images of galaxies far beyond our Local Group.

GaBany’s images have revealed faint tidal streams and rings in the outer halos of large spiral galaxies, indicative of recent and ongoing gravitational interactions with dwarf satellite galaxies. These images are helping scientists better understand how large galaxies such as our own Milky Way are built up through the collisions and mergers of many smaller galaxies.

Observing under very dark skies, and using very sensitive cameras, long exposure times, and advanced imaging and processing techniques, GaBany has managed to capture details not seen in professional images. Papers based on GaBany’s images have been published in leading scientific journals such as the Astrophysical Journal, the Astronomical Journal, and Astronomy & Astrophysics, with GaBany being listed as a coauthor.

"It has been an amazing adventure that, thankfully, has not ended," says GaBany. "I never dreamed that Dr. Martinez-Delgado’s invitation to participate in his research group would result in a multi-year relationship and transport me on a modern day voyage of discovery. While professionals and amateurs commonly collaborate on planetary research, I realize such associations involving astrophysicists are rare. It’s a great honor to receive the AAS’s Chambliss Award."

"I came to know Jay in March 2006 when I chanced upon his web site of astrophotos and was struck by an image of the galaxy M94 that displayed never-before-seen structure in the faint outer halo surrounding the galaxy," recalls Martinez-Delgado. "I quickly realized he possessed enthusiasm, time, talent, and research-grade instruments that could be beneficial to my projects. So I invited him to join my team of professional researchers. He accepted, and we have been working together ever since in what has proven to be an extremely fruitful example of professional-amateur collaboration."

Galaxy researcher Steven Majewski of the University of Virginia adds, "I can think of no one more deserving of such recognition than Jay, who has single-handedly, through his dedicated and careful work, spawned a new research direction in the exploration of galaxy evolution. His images of the galaxies NGC 5907, NGC 4013, and other disk systems absolutely blow away the previous professional attempts, and reveal complex, multi-wrapped tidal streams around these Milky Way analogs."

"I am very excited by Jay GaBany’s selection as the winner of the Chambliss Award for Amateur Achievement," adds Vassar College astronomer Debra Elmegreen, President of the AAS. "Amateurs are increasingly playing more and more prominent roles in aiding and collaborating with professional astronomers in research. Mr. GaBany's work crosses the line from amateur into professional research; his techniques to enhance faint features are quite sophisticated, and his deep images of the outer parts of galaxies are not just pretty pictures but have changed the way we see galaxies and helped guide our thinking about the connections between galaxies."

At its 217th semi-annual meeting last week in Seattle, Washington, the American Astronomical Society (AAS) named the recipients of its 2011 prizes for achievements in research, instrument development, education, and writing. The honorees range from college students to distinguished senior astronomers.

The Society’s prestigious Henry Norris Russell Lectureship went to Dr. Sandra M. Faber (University of California, Santa Cruz) "for a lifetime of seminal contributions to galaxy evolution and dynamics, the distribution of the mysterious ‘dark matter’ in the universe, for leading the construction of astronomical instrumentation, and for mentoring future leading astronomers."

The Newton Lacy Pierce Prize for outstanding achievement in observational research by an early-career astronomer went to Dr. Gaspar Bakos (Harvard-Smithsonian Center for Astrophysics) "for the impact he has had on the study of exoplanets, his contributions to our understanding of the unexpected diversity of exoplanet properties, and the extraordinary entrepreneurial spirit and capability he has shown in the development of one of the most successful systems for detecting transiting extrasolar planets (HATNet)."

The Helen B. Warner Prize for a significant contribution to observational or theoretical astronomy by an early-career scientist went to Dr. Steven R. Furlanetto (University of California, Los Angeles) "for his theoretical work in the field of high-redshift cosmology, including groundbreaking work on the epoch of reionization and its observational signatures, opening up new pathways to the study of reionization in the redshifted 21-cm hydrogen line."

This year’s Joseph Weber Award for instrumentation went to Dr. Edward S. Cheng (Conceptual Analytics, Glenn Dale, Maryland) "for his critical contributions to the development of several key instruments on the Hubble Space Telescope," in particular his efforts toward the creation and/or repair of three of Hubble’s cameras and spectrographs.

The Dannie Heineman Prize in Astrophysics, awarded in partnership with the American Institute of Physics, recognizes outstanding work by mid-career astronomers. The 2011 Heineman Prize goes to Dr. Robert P. Kirshner (Harvard-Smithsonian Center for Astrophysics) "for his sustained and enduring contributions to our understanding of supernovae and cosmology." The award committee called special attention to Kirshner’s work with students using supernova light curves as calibrated standard candles, which has provided evidence for an accelerating expansion of the universe. "The dark energy inferred from this result is one of the deepest mysteries of modern science."

The George Van Biesbroeck Prize honors a living individual for long-term extraordinary or unselfish service to astronomy. Dr. David S. Leckrone (NASA Goddard Space Flight Center) is this year’s recipient. The AAS celebrated his "three decades of selfless dedication to the instrumenting, servicing, and science programs of the Hubble Space Telescope, through informed advocacy, technical management, and outreach to diverse constituencies in education, government, the science community, and the general public."

The 2011 Education Prize was awarded to Dr. Grace Deming (University of Maryland, College Park) "for blazing the trail of astronomy education research; providing us with the Astronomy Diagnostic Test, the first means within our discipline to assess the success of our instruction; tirelessly promoting the use of research to guide our instruction; and educating us about the importance of collaborative group learning to improve student understanding."

The Annie Jump Cannon Award for outstanding research and promise for future research by a woman went to Dr. Rachel Mandelbaum (Princeton University) "for her groundbreaking contributions to the field of weak gravitational lensing of galaxies. Her work on understanding and eliminating numerous systematic effects inherent in weak lensing data have advanced this technique to the point where it can now be used with confidence for precision cosmology."

The Chambliss Astronomical Writing Award for an academic book went to Dr. Hale Bradt (Massachusetts Institute of Technology) for Astrophysics Processes: The Physics of Astronomical Phenomena (Cambridge University Press, 2008). Said one reviewer, "The author’s engaging writing style makes this a very enjoyable book. Each topic starts with interesting observational material, then goes to a discussion of the physical concepts, amplified by mathematics, and very good figures, and then ties it up by finishing with more observational applications, either solving the problem posed at the beginning of the chapter or presenting new ones."

Recognizing the contribution of nonprofessionals to the advancement of astronomical research, the AAS gave the Chambliss Amateur Achievement Award to R. Jay GaBany of San Jose, California, "who has single-handedly, through his dedicated and careful work, spawned a new research direction in the exploration of galaxy evolution via low-surface-brightness imaging of galaxy halo substructure." GaBany has devoted hundreds of hours working with professional astronomers to make deep images that reveal faint tidal streams and rings in the outer halos of galaxies, indicative of recent and ongoing galaxy interactions with dwarf satellites, supporting studies of galaxy formation.

At the Seattle AAS meeting, more than 300 students presented poster papers based on their research and competed for the Chambliss Astronomy Achievement Student Awards. Seventy-three professional astronomers fanned out across the exhibit hall to judge these presentations over several days, resulting in the awarding of 14 Chambliss medals for exemplary research.

Background information



About R. Jay GaBany


R. Jay GaBany is a San Francisco, California Bay Area astrophotographer whose home is in San Jose. Jay's interest in astronomy began at a very young age when he watched Sputnik pass overhead while perched on his father's shoulders. An active visual observer for over thirty years, Jay traded his oculars for a CCD camera shortly following the turn of the 21st century.

His initial attempts at imaging from a light polluted backyard were abandoned in favor of a remotely controlled observatory situated high in the south central mountains of New Mexico under pristine, clear, dark skies. For the past several years, Jay has been collaborating with an international team of professional astronomers, led by Dr. David Martínez-Delgado (Max Planck Institute for Astronomy and Instituto de Astrofísica de Canarias), in search of stellar streams around nearby galaxies in addition to producing interesting deep sky images of familiar subjects.

GaBany is a member of the Board of Directors for the annual Advanced Imaging Conference and a former member of the Kitt Peak Visitor Center Advisory Board. He has been asked to speak before various audiences, interviewed on live radio, written almost fifty articles for the daily web magazine/blog called Universe Today, featured in Wired and Discover magazine articles and received an award from the industry's leading astronomical camera manufacturer, SBIG. Over 90% of his astronomical images have been published in leading domestic and international magazines, books and television productions.

Ghosts of galaxies
(from the Instituto de Astrofísica de Canarias news release 4/8/2008)

An international team of astronomers has identified huge star streams in the outskirts of two nearby spiral galaxies. For the first time, they have obtained a panoramic overview of an example of galactic cannibalism similar to that involving the Sagittarius dwarf galaxy in the vicinity of the Milky Way.

The detection of these immense stellar fossils confirms the predictions of the cold dark matter model of cosmology, which proposes that present-day grand design spiral galaxies were formed from the merging of less massive stellar systems. The first of these debris structures surrounds the galaxy NGC 5907, located 40 million light-years from Earth and formed from the destruction of one of its dwarf satellite galaxies at least four thousand million years ago.

According to the research team, the dwarf galaxy has lost the greater part of its mass in the form of stars, star clusters and dark matter, all of which has become strewn out along its orbit, giving rise to a complicated assembly of crisscrossing galactic fossils whose radius exceeds 150 000 light-years.

"Our results provide insight into this spectacular phenomenon surrounding spiral galaxies and show that haloes contain fossil dwarf galaxies, a unique opportunity to study the final stages of assembly of galaxies like ours," says David Martínez, a researcher the Instituto de Astrofisica de Canarias (IAC) led the team that conducted the observations. The astronomers’ search has not been able to find the main bodies of the devoured galaxies, which leads them to conclude that they have by now been completely destroyed."

"These star streams are very difficult to detect and have a very low density of stars," comments Martínez. "It is this that gives them their ghostly aspect. Hence, being related with the death of a dwarf galaxy, they may be considered as the ghosts of now vanished galaxies." said Martinez.

The team has discovered another huge, tenuous stream in the shape of a loop in the galaxy NGC 4013, almost 50 million light-years away in the constellation Ursa Major. Its ghostly trail stretches more than 80 000 light-years from the nucleus and is made up of old, metal-poor stars. Although its three-dimensional geometry is unknown, it possesses a structure very similar to that of the Monoceros tidal stream, a ring of stars surrounding the Milky Way that was formed through the destruction of a dwarf galaxy three thousand million years ago.

Jorge Peñarrubia, a theoretical astrophysicist at the University of Victoria (Canada) and member of the team, specializes in modeling these star streams. According to Peñarrubia, "fitting theoretical models to these star streams enables us to reconstruct their history and describe one of the most mysterious and controversial components of galaxies: dark matter."

For the job of seeking out and detecting the streams, the team has enlisted the help of the renowned astrophotographer R. Jay Gabany, whose contribution towards obtaining the images "has been decisive," says Martínez, "a fact that underlines yet again the great contribution made by amateurs."

For years, R. Jay Gabany has obtained spectacular color images of the deep sky with small robotic telescopes in New Mexico and Australia. His images have been published in the best popular astronomy magazines in the world. His work on this project demonstrates the potential contribution of amateur astronomers to twenty-first century astronomy. With the new technologies, they are capable of participating in highly competitive scientific projects at an international level.

Spirals eat dwarfs: Galactic tendrils shed light on evolution of spiral galaxies
(from the MPIA Science Release 2010-09-07)

Around the Milky Way galaxy and in the vicinity of our immediate cosmic neighborhood, known as the Local Group of galaxies, traces of spiral galaxies swallowing dwarf galaxies have been known since 1997. But the Local group with its three spiral galaxies and numerous dwarfs is much too small a sample to see whether theoretical predictions of the frequency of such digestive processes match observations. Now, for the first time, a new survey has managed to detect the tell-tale tendrils of galactic digestion beyond the Local Group. An international group of researchers led by Dr. David Martínez-Delgado (Max Planck Institute for Astronomy and Instituto de Astrofísica de Canarias) has completed a pilot survey of spiral galaxies at distances of up to 50 million light-years from Earth, discovering the tell-tale signs of spirals eating dwarfs.

When a spiral galaxy is approached by a much smaller companion, such as a dwarf galaxy, the larger galaxy's uneven gravitational pull severely distorts the smaller star system. Over the course of a few billions of years, tendril-like structures develop that can be detected by sensitive observation. In one typical outcome, the smaller galaxy is transformed into an elongated tidal stream consisting of stars that, over the course of additional billions of years, will join the galaxy's regular stellar inventory through a process of complete assimilation. The study shows that major tidal streams with masses between 1 and 5 percent of the galaxy's total mass are quite common in spiral galaxies.

Detailed simulations depicting the evolution of galaxies predict both tidal streams and a number of other distinct features that indicate mergers, such as giant debris clouds or jet-like features emerging from galactic discs. Interestingly, all these various features are indeed seen in the new observations impressive evidence that current models of galaxy evolution are indeed on the right track.

The ultra-deep images obtained by Delgado and his colleagues open the door to a new round of systematic galactic interaction studies. Next, with a more complete survey that is currently in progress, the researchers intend to subject the current models to more quantitative tests, checking whether current simulations make the correct predictions for the relative frequency of the different morphological features.

Remarkably, these cutting-edge results were obtained with the telescopes of ambitious amateur astronomers: For their observations, the researchers used telescopes with apertures between 10 and 50 cm, equipped with commercially available CCD cameras. The telescopes are robotic (that is, they can be controlled remotely), and are located at two private observatories in the US and one in Australia. The results attest to the power of systematic work that is possible even with smaller instruments: While larger telescopes have the undeniable edge in detecting very distant, but comparatively bright star systems such as active galaxies, this survey provides some of the deepest insight yet when it comes to detecting ordinary galaxies that are similar to our own cosmic home, the Milky Way.

The research group consists of David Martínez-Delgado (Max Planck Institute for Astronomy, Heidelberg, Germany, and Instituto de Astrofísica de Canarias, Spain), R. Jay Gabany (Black Bird Observatory), Ken Crawford (Rancho del Sol Observatory), Stefano Zibetti and Hans-Walter Rix (Max Planck Institute for Astronomy), Steven R. Majewski and David A. McDavid (University of Virginia), Jürgen Fliri (Instituto de Astrofísica de Canarias and Observatoire de Paris, Meudon), Julio A. Carballo-Bello and Ignacio Trujillo (Instituto de Astrofísica de Canarias), Daniella C. Bardalez-Gagliuffi (MIT and Instituto de Astrofísica de Canarias), Jorge Penarrubia (Cambridge University), Taylor S. Chonis (University of Texas), Barry Madore (Carnegie Institution of Washington) and Mischa Schirmer (Argelander Institute for Astronomy, Bonn University).

M 94: A New Perspective

In 2006, this ground based optical (white light) image attracted the attention of an international team of astronomers, led by Dr. David. Martínez-Delgado (MPIA and IAC) and Ignacio Trujillo (IAC), who launched a three year investigation that probed M 94 (NGC 4736) in multiple wavelengths. Optical images typically display this star system as an active central region surrounded by an amorphous circular band of gas, dust and stars classically described as a closed stellar ring.

However, modern astronomical CCD cameras possess an incredible tonal range- far more than photographs produced with film emulsions. So, if great care is exercised with digital dark room techniques, it's possible to preserve and enhance small contrast variances captured by modern electronic imaging chips that are often overlooked. For M 94, the result is an optical image that offers a tantalizing glimpse of a classic spiral pattern hidden within the surrounding ring.

The space between the stars is not empty- it's filled with very thin amounts of molecular gas and dust. But, even a few molecules of this material per cubic centimeter can create a dense, opaque cloud when viewed from a distance of a hundred or more light years. These clouds can absorb the white light released by stars that lie further beyond making it difficult or impossible for us to see them visually. But, ultraviolet and infrared radiation often provides a different perspective. This enables astronomers to pierce otherwise obscuring haze with images taken through filters that only pass these wavelengths. For example, ultraviolet images can reveal active star forming regions where the gas and dust is thin. Mid and far infrared pictures can capture gas and dust structures heated by stars in relative close proximity.

Our investigation detected furious stellar formation (about twice that occurring in the central disk), confirmed the existence of an impressive set of spiral arms extending throughout the surrounding ring and provided an explanation about their origin when M 94 was studied through mid-infrared, near and far ultraviolet wavelengths.

The presence of bars at the center of galaxies can introduce instabilities that result in the formation of spiral arms. Interestingly, galactic bars can be quite broad. These fat bars, also known as oval distortions, often resemble a normal, slightly inclined disk with spiral arms. Previous researchers considered the inner disk of M 94 to be an oval distortion. The results of our team's study supports their conclusions and considers it to be the most plausible explanation for the inner ring, the previously undetected spiral structure and enhanced new star formation in the outer disk of M 94.
