Kelle Cruz - Co-Grad Chair, AMNH-CUNY Liaison (Hunter College)
Prof. Cruz is part of the BDNYC collaboration
and her research focuses on the observational study of brown dwarfs and very low-mass stars. Brown dwarfs form like stars, but unlike stars, they cool over time have radii, masses, and temperatures similar to giant gas planets like Jupiter. She uses optical and/or near-infrared spectroscopy (0.6–5 microns) on telescopes in Hawaii, Chile, and Arizona to collect data on these objects and uses specialized computer software (e.g., IRAF, IDL, Python) and custom programming to do the analysis. Much of her research concentrates on creating a volume-complete sample of very low-mass stars and brown dwarfs and using that sample to undertake statistically robust studies of their physical properties. She also is currently studying juvenile brown dwarfs, only recently discovered, that have ages likely between 10 and 100 Myr and masses between ~10 and 30 Jupiter masses. Much of her current research efforts are focused on getting more accurate ages for these objects and using them to identify and calibrate age indicators in brown dwarfs. Prof. Cruz is also the founder and editor for AstroBetter
, a blog and wiki site for professional astronomers.

Saavik Ford - Co-Undergrad Chair (Borough of Manhattan Community College)
Prof. Ford works on Active Galactic Nuclei (AGN)---galaxies which appear to have an accreting black hole and/or significant star formation in their nuclei. Her primary interest is in studying the structures that allow accretion onto black holes and how matter fueling activity arrives in the nucleus. She primarily uses high-contrast, high-resolution imaging, and is also working with a new kind of optical interferometric technique called non-redundant masking.

Prof. Liu conducts research primarily on colliding galaxies, starburst galaxies, and the star formation history of the universe. He is a co-investigator of COSMOS
, an international cosmic evolution survey anchored on the largest contiguous area of sky ever imaged by the Hubble Space Telescope. Using both ground-based and space-based observatories, he studies changes in galaxy populations over the past 10 billion years of cosmic time, and probes how those changes might foreshadow the future evolution of our own Milky Way Galaxy and the universe as a whole. Prof. Liu has also authored and co-authored numerous books and articles presenting astronomy to general audiences, including One Universe: At Home In The Cosmos
(2000, Joseph Henry Press, with Neil Tyson and Robert Irion) and The Handy Astronomy Answer Book
(2014 [3rd edition], Visible Ink Press). Currently, he is also serving as the faculty director of Macaulay Honors College
and The Verrazano School
at the College of Staten Island.

Ariyeh Maller - Co-Grad Chair (City Tech)
Prof. Maller's research focuses on the formation and evolution of galaxies. He pursues this through a variety of methods, running hydrodynamical simulations, working with analytic and semi-analytic models, and by analyzing observations in ways more suited for comparison with theoretical model. One of his primary interests is in understanding the gaseous halos of galaxies, which provide the fuel for future star formation. He is also active in studying dust in spiral galaxies, quasar absorption systems and their local analogs, how galaxies get their angular momentum and gravitational lensing by spiral galaxies.

Barry McKernan (Borough of Manhattan Community College)
Prof. McKernan studies the central engine of active galactic nuclei (AGN). He uses X-ray and infrared observations of AGN to constrain models of accretion onto supermassive black holes. He also carries out theoretical studies of fueling of AGN and is interested in MHD simulations of the central engine. He is part of a team applying a new detector technique to space telescopes in order to image details in AGN.

Quinn Minor (Borough of Manhattan Community College)
Prof. Minor's research focuses primarily on dark matter in dwarf spheroidal galaxies, which are among the most dark matter-dominated objects in the universe. With an eye toward elucidating the particle nature of dark matter, he is developing statistical tools to extract the amount and distribution of dark matter in dwarf galaxies from spectroscopic data sets. He also studies binary star populations in these galaxies, comparing binary properties in different populations to test the universality of the star formation process. Dr. Minor is also interested in using strong gravitational lensing to probe dark matter halo structure and substructure, particularly from upcoming sky surveys such as LSST, and has written software to simulate gravitational lenses for this purpose.

Timothy Paglione - Chair (York College)
Prof. Paglione's main field is microwave spectroscopy of interstellar molecular clouds. He studies primarily the very largest clouds in galaxies, which form the most massive stars. These stars live furiously, greatly affecting their surroundings with their winds and radiation, then die dramatically in giant explosions that enrich the interstellar medium in heavy elements. Their lives are relatively brief as well ("only" 10 million years or less) so their impact is not only profound but immediate. Certain galaxies known as starbursts create numerous clusters of these massive stars in their centers. Dr. Paglione studies the gas that forms these stars in starbursts and in our own, normal, Milky Way Galaxy, estimating and their physical properties and comparing them with the galaxy dynamics. Not limited only to the radio, Dr. Paglione also studies the gamma-ray emission from starburst galaxies, which originates from their numerous supernovae and a cascade of particle reactions and high energy emission mechanisms.

Prof. Rice's research combines observational and theoretical approaches for a comprehensive spectroscopic study of cool atmospheres, including very low mass stars, brown dwarfs, and giant extra-solar planets. Prof. Rice uses observational spectra from telescopes in Hawaii and California and synthetic spectra from model atmospheres created with the PHOENIX radiative transfer code. Brown dwarfs and gas giant planets continually cool, shrink, and fade as they age, meaning they are hotter, larger, and brighter when they are younger, resembling very low mass stars. Therefore their atmospheric properties are similar, although the objects are at different evolutionary stages. A comprehensive understanding of these very low mass objects is necessary for understanding star and planetary formation, calibrating stellar and substellar evolution models, and accurately inferring the atmospheric properties of gas giant planets.
