David Meyer  [Meyer personal page]
Professor Meyer's research specialty is the study of interstellar and extragalactic gas clouds through ultraviolet and optical absorption-line spectroscopy. Over the past several years, he has focused on problems involving the small-scale structure of the interstellar medium (ISM) and the elemental abundance patterns of the Galactic ISM and quasar absorption-line systems.

Giles Novak
Professor Novak observes the polarization of infrared and sub-millimeter thermal emission from magnetically aligned interstellar dust grains. The resulting magnetic field maps are being used to determine the role of magnetic fields in diverse environments such as the Galactic center, giant molecular clouds, and star-forming regions.

Mel Ulmer
Professor Mel Ulmer's research concentrates on the formation and evolution of clusters of galaxies using X-ray, optical, and infrared observations. Of particular interest are the physical characteristics of the intracluster gas, the possible existence of cooling flows and the X-ray and gamma-ray observations of pulsars.

Farhad Yusef-Zadeh  [Yusef-Zadeh personal page]
Professor Yusef-Zadeh uses radio, infrared and X-ray telescopes to study phenomena that has been observed in the rich, complex center of the Milky Way Galaxy. Understanding the nature of the phenomena in the Galactic center can improve our overall view of how the central engines (thought to be massive black holes) in Active Galactic Nuclei derive their power and characteristics.
