The ATLAS team includes astronomers and engineers from the University of Hawaii and the Space Telescope Science Institute as well as volunteers who provide important support. We are dedicated to making the world safer from asteroid impacts. All of us are enthusiastic about coupling state-of-the-art camera technology to sophisticated computerized image processing in order to take advantage of what modern computers can do for astronomy.

John Tonry, University of Hawaii

John Tonry received his PhD from Harvard in 1980, was a post-doctoral fellow at the Institute for Advanced Study and Caltech, and then became a faculty member in the physics department at MIT. After 11 years the lure of Hawaii became too great to resist and he joined the University of Hawaii's Institute for Astronomy in 1996. John has been heavily involved in using high redshift supernovae (SNIa) to measure cosmological parameters as well as other research projects such as studying black holes in galaxy centers and determining distances to nearby galaxies. He and the rest of the High-Z team discovered the accelerating expansion of the universe from dark energy in 1998 and have continued ever since identifying and following SNIa to refine those measurements. He and his students have developed new methods to characterize SNIa from their spectra and measure distances from their light curves, and eagerly using the new information from Pan-STARRS1.

John is one of the principals who initiated and led the Pan-STARRS project to the construction of the first prototype telescope, Pan-STARRS1 on Haleakala. He led and managed the $7M effort to build the Pan-STARRS GPC1 Camera - the world's first gigapixel camera. (The LSST camera, at twice the pixel count, is budgeted to cost more than 10 times as much.) GPC1 was ready for use in Aug 2007 and has operated since then without significant problem. He continues as a consultant for the engineers who are presently building GPC2.

Larry Denneau, University of Hawaii

ATLAS senior software engineer Larry Denneau has been the chief software architect of the Pan-STARRS moving object processing system (MOPS) since 2004. MOPS is a software package that automatically identifies solar system objects (in particular hazardous asteroids) in the Pan-STARRS data stream. To date Pan-STARRS has discovered over 500 near-Earth objects and 30 comets.

Larry has been poking at computer keyboards since the early 80s and received his B.S.E.E. from the University of Arizona, whereupon he quickly escaped academia. His software career has spanned projects ranging from surface metrology for the semiconductor industry, medical scheduling, geophysical instrumentation, and a dot-com Internet startup that actually turned a profit. Now back in academia, Larry has enthusiastically joined the effort to protect the earth from dangerous asteroids.

Brian Stalder, Post-doctoral Fellow, University of Hawaii

Brian received his PhD at the IfA in 2007, studying the optical properties of high redshift radio galaxies and testing detectors and developing prototype cameras in the Pan-STARRS camera group. Upon graduating, he joined a team at Harvard University and Smithsonian Astrophysical Observatory leading the camera design and construction of PISCO, a simultaneous 4-band optical imager to be installed at the Magellan Observatory in Chile. He is also a developer of the Stellar Locus Regression technique for fast photometric calibration of astronomical data.

While in Cambridge, he also became involved in Antarctic radio astronomy. Since 2008, he has been a collaborator on the South Pole Telescope project (a 10-meter millimeter wavelength telescope at the Geographic South Pole), working on the data analysis pipeline and leading the optical and infrared follow up of massive distant galaxy clusters detected via the SZ effect. He also contributes to the Stratospheric Terahertz Observatory (0.8-meter heterodyne survey telescope operating at 1.4 and 1.9 THz) long-duration balloon project, first launched during the 2011-2012 season, dealing with the hardware alignment of the optics and data processing.

Ari Heinze, Post-doctoral Fellow, University of Hawaii

Aren (Ari) Heinze studied Pluto as an undergraduate at Caltech and searched for extrasolar planets as a graduate student at the University of Arizona (PhD 2007). As a visiting professor at Swarthmore College (2007-2009), he made the first accurate measurement of the dwarf planet Makemake's rotation period, finding that any future spacefarers on this Kuiper Belt object will see a distant sunrise every 7.77 hrs. Ari self-published a fantasy epic in 2010, and in late 2011 returned happily to academia as a postdoc at Stony Brook University. There he used data from the Spitzer Space Telescope to study the exotic iron-vapor clouds and rapidly changing weather of brown dwarfs, and became increasingly fascinated by the quest to find and catalog new asteroids. He joined ATLAS to become a professional asteroid-hunter in August 2015.

Armin Rest, Space Telescope Science Institute

Armin Rest came to the US as a Baden-Wuerttemberg - Oregon exchange student at the Physics Department of Portland State University where he received his M.S. in physics. He decided to stay in the United States and received his Ph.D. in Astronomy from the University of Washington. As a NOAO Goldberg fellow he then spent 4 years at Cerro Tololo Interamerican Observatory in La Serena, Chile where he was one of the leaders of the SuperMACHO and ESSENCE projects, two time-domain sky surveys that investigate dark matter and dark energy, respectively.

Armin's research interests have mainly been focussed on observational cosmology with a particular emphasis on detection and analysis of rare transient events. i.e. things in our universe that happen infrequently and last for only short periods of time. Returning from Chile, he worked for three years at Harvard University where his focus shifted toward PanSTARRS, the next big wide-field, time-domain survey, as well as following up galaxy cluster candidates detected by the South Pole Telescope via the Sunyaev-Zeldovich effect. He also leads a group investigating light echoes of ancient and historic supernovae. In 2010 Armin accepted a position as an assistant astronomer at the Space Telescope Science Institute in Baltimore, MD.

Stephen Smartt, Queen's University, Belfast

Stephen Smartt received his PhD from Queen’s in 1996, was a support astronomer at the Isaac Newton Group of Telescopes on La Palma and then a postdoc at the University of Cambridge. He is a former holder of a UK Advanced Fellowship from PPARC (now STFC) and a European Young Investigator Award. He is Director of the Astrophysics Research Centre at Queen’s and works on supernovae and their progenitor stars. With his team of students and postdocs he has characterised the progenitors of the local core-collapse supernova population. The progenitors have been directly identified before explosion allowing spectral types and masses to be estimated. His team have studied the origin of superluminous supernovae, their explosion mechanisms, and dwarf host galaxies. The team has developed techniques to rapidly identify and characterize supernovae in wide-field surveys, particularly with the Pan-STARRS surveys. He is PI and Survey Director of PESSTO, the Public ESO Spectroscopic Survey of Transient Objects, which is ESO’s major currently running supernova survey.

Ken Smith, Queens University, Belfast

Ken Smith graduated in Electronics at Ulster University, Coleraine, then went on to do a PhD in Scanning Tunnelling Microscopy at Queen’s University Belfast, developing software to render 3D surface topographic images of conducting materials and studying surface diffusion of gold at the atomic scale. This was followed by a nearly 4-year postdoc in condensed matter physics. He then left physics and worked as a software engineer for British Telecommunications for over a decade, specialising in authentication and large customer databases. In 2009 he returned to academia to work on developing static transient object databases for Pan-STARRS1. He now develops and runs a descendent of that - the Pan-STARRS Search for Transients (PSST) - and is involved in developing software for the Public ESO Spectroscopic Survey for Transient Objects (PESSTO). He's currently developing static transient object database(s) for ATLAS.

Phil Whitney

[Phil Whitney at IfA. Image credit: Karen Rehbock, University of Hawaii Institute for Astronomy. From]Phil Whitney is one of the IfA's most enthusiastic supporters. He joined the Friends of Hawaii Astronomy in 2000, the first year of the group's existence, and attends many IfA functions. He also lends a welcome helping hand at IfA's popularannual open house, where he tries to recruit new "Friends."

At the IfA, Whitney is fondly known as "Mr. Rotary Club" because, since 1999, he has arranged for IfA astronomers to give talks to many of the Oahu Rotary clubs. (He is an active member and past president of the Rotary Club of Honolulu.) Astronomer Paul Coleman says that he loves giving talks to the various Rotary clubs because "Phil picks me up at the Institute, drives me to the meetings, treats me to lunch, lets me give my talk, and afterwards returns me back to the office."

Whitney's interest in astronomy goes back many years to when he first read works by George Gamow and Fred Hoyle (known for their work related to cosmogenesis) and Arthur C. Clarke (inventor of the geosynchronous communications satellite, but better known for writing science fiction). This interest was revived as he neared retirement: "In 1998 I was beginning a transition to full retirement and saw an article on the Institute, and this rekindled my interest in astronomy." He made a phone call to the IfA Director's Office, received a packet of information, visited, and soon started arranging Rotary talks. Whitney says, "I feel very fortunate to associate with such a professional, forward-looking group that is bringing new knowledge to the world and important economic and educational benefits to our state." He is one of the early and continuing donors among a group that recognizes the importance of ATLAS.

In Memoriam

Andrei Sherstyuk

Andrei Sherstuyk joined the ATLAS project as a software engineer in 2013. He was heavily involved with the development of ATLAS 1 and ATLAS 2 observatories. Tragically, he suffered a fatal heart attack at the Institute for Astronomy on August 4th, 2016. 

Andrei Sherstyuk received his Ph.D. from Monash University, Australia for his research on Convolution Surfaces in Computer Graphics, in 1999. Intrigued by the use of CG in the movie industry, he worked on the first photo-realistic feature, "Final Fantasy: The Spirits Within," and a number of role-playing games featuring human avatars. In 2002, Andrei returned to academia and spent several years designing and developing interactive Virtual Reality systems for medical research and education at the John A. Burns School of Medicine at the University of Hawai'i (JABSOM). His products are used in clinical research at Tripler Army Medical Center in Honolulu.

Andrei authored papers on fundamental computer graphics algorithms and on human-computer interactions that focus on Virtual Reality and its applications. He was a member of the Association for Computing Machinery (ACM) and of the Institute of Electrical and Electronics Engineers (IEEE). He belonged to the International Program Committees of multiple Virtual Reality conferences. Andrei had several patents pending involving computer graphics.
