Astronomy Research Faculty - All

Professor Pauline Barmby Dr. Pauline Barmby
Research Areas: My research is in the investigation of galaxy histories. Using multi-wavelength imaging from telescopes on the ground and in space, I study recent star formation, the properties of star clusters, and mass-losing stars in nearby galaxies.

Professor Shantanu Basu Dr. Shantanu Basu - Department Chair
Research Areas: I study the dynamics of star and planet formation, as well as that of the larger interstellar medium. Current topics of interest include the fragmentation properties of interstellar clouds, the formation and evolution of circumstellar disks, magnetic fields in the near-stellar environment, and applications of mathematical and statistical methods to astrophysics.

Professor Peter Brown Dr. Peter Brown
Research Areas: I am interested in answering basic questions about the origin and evolution of small bodies in the solar system. These include the origin of metoroids,the origin of meteorites, the physical structure of meteoroids and the flux and interaction of larger meteoroids at Earth.

Professor Jan Cami Dr. Jan Cami
Research Areas: My main interest is in the circumstellar matter surrounding evolved stars (AGB stars) and in the astrochemistry of the interstellar medium although I have studied the molecular content and dynamics of external galaxies as well. I study the Diffuse Interstellar Bands (DIBs) and their relation to Polycyclic Aromatic Hydrocarbons (PAHs).

Professor Margaret Campbell-Brown Dr. Margaret Campbell-Brown
Research Areas: Millions of meteoroids, which are fragments of comets and asteroids, hit the Earth each day. These objects provide an opportunity to study the distribution and composition of many comets and asteroids. High-resolution images of meteoroids ablating in the atmosphere can be used to determine their composition, and continuous radar observations have a wealth of information about the history and current state of small bodies in our solar system.

Professor Sarah Gallagher Dr. Sarah Gallagher
Research Areas: My research encompasses multiwavelength programs concerning the co-evolution of supermassive black holes and their host galaxies. Specifically, I study energetic quasar winds, and galaxy evolution and star formation in compact galaxy groups.

Professor David F. Gray Dr. David F. Gray
Research Areas: Stars are not only beautiful, but are one of the cornerstones of astronomy. I study starlight and from it deduce interesting physical characteristics such as a star's rotation rate, the nature of the gas motions (called granulation) at the surface, pulsations & oscillations, and magnetic cycles similar to the sun's 10 year pattern. My work also includes getting precise stellar temperature and some of the most accurate radial velocities yet determined.

Professor Richard Holt Dr. Richard Holt
Research Areas: The Atomic Physics & Laboratory Astrophysics group uses fast-ion-beam laser spectroscopy techniques to measure properties of atoms of astrophysical and fundamental interest. The results have an impact on studies of Galactic nucleosynthesis, stellar interiors, and tests of calculations of relativistic and quantum electrodynamic effects in two-electron atomic systems.

Professor Martin Houde Dr. Martin Houde
Research Areas: My research is focused on understanding the physical processes that lead to the formation of stars. A substantial part of my efforts is concerned with characterizing the magnetic fields and turbulence that are believed to be important agents that determine the physical conditions in molecular clouds, sites of star formation. My research group also develops and tests instruments within the Submillimetre Astronomical Laboratory, which are then deployed at premier millimetre/submillimetre astronomical observatories.

Professor Carol Jones Dr. Carol Jones
Research Areas: Circumstellar material is common among massive, early-type stars and often takes the form of an equatorial disk.

I construct computational models of these disks to try to understand how they form and what their physical conditions are. Numerical radiative transfer techniques are used to predict spectra and images of the circumstellar material. Models are constrained by comparison to images obtained via the rapidly developing field of optical interferometry and to spectroscopy obtained at a wide variety of wavelengths. This research offers many computationally challenging problems.

Professor John D. Landstreet Dr. John D. Landstreet
Research Areas: I model the intensity and polarisation spectra of various types of stars to try to extract information about the physical state (chemical abundances, presence of convection or of a magnetic field, etc) and atmospheric physical processes (mass loss, mixing, diffusion, etc) in those stars.

Professor Els Peeters Dr. Els Peeters
Research Areas: I use observational data to study molecules and dust in interstellar and circumstellar environments, in particular galactic and extragalactic star forming regions. My main focus is the study of Polycyclic Aromatic Hydrocarbon molecules (PAHs).

Professor Aaron Sigut Dr. Aaron Sigut
Research Areas: My main research interests are the radiative transfer and hydrodynamical processes occurring in circumstellar disks surrounding hot stars. I also have research projects involving the modeling of the emission line spectra of active galactic nuclei and the quantitative analysis of stellar atmospheres using non-LTE radiative transfer. All of my research projects involve large-scale, computational modeling.

Professor Paul Wiegert Dr. Paul Wiegert
Research Areas: I'm interested in the dynamics of the Solar System, particularly its smaller bodies, asteroids, comets and meteoroid streams. I'm also interested in the dynamics of planets around other stars, and in celestial mechanics in general.
