UNT has an active astrophysics research group with experts in observational and theoretical extragalactic astrophysics conducting cutting-edge investigations. The group consists of several graduate and undergraduate students and is funded regularly by the National Aeronautics and Space Administration and the National Science Foundation.

Dr. Yuan Li works in the field of galaxy evolution. She is mainly a theoretical/computational astrophysicist but occasionally works on observational data as well. Her research interests include galaxies, galaxy clusters, supermassive black hole accretion and feedback, the interstellar medium, the intra-cluster medium, and the circum-galactic medium.

Dr. Ohad Shemmer works on multiwavelength observations of active galactic nuclei (AGN). His research interests include studying high-redshift quasars to trace the growth of supermassive black holes, AGN variability, and deriving fundamental quasar properties reliably through multiwavelength spectroscopy.

Dr. Fakhri Zahedy is an observational astronomer working in galaxy formation and evolution. He is interested in understanding how the gaseous reservoir of a galaxy determines the course of its evolution. Dr. Zahedy uses large ground-based and space telescopes to study low-density gas within and surrounding distant galaxies and investigate how galaxy properties depend on those of the gas.
