Extragalactic & Cosmology

The extragalactic group at the University of Florida investigates the formation and evolution of structure on galactic to cosmological scales. Members of the group conduct research on a diverse array of topics including active galactic nuclei, galaxy formation and evolution, galaxy cluster assembly, and dark matter.


Faculty Research

Our extragalactic group focuses on Active Galactic Nuclei, Galaxy Formation and Evolution, Galaxy Structure, Galaxy Clusters, Galaxy Clustering, Dark Matter, Structure Formation, Observational Cosmology, Electromagnetic Observations of Gravitational Wave Candidates.

Stephen Eikenberry is a member of the LIGO collaboration and develops instrumentation for extragalactic programs.

Jian Ge conducts research related to AGN variability, and dust and gas properties around quasars.

Anthony Gonzalez investigates a range of topics in galaxy evolution and observational cosmology. His current interests include galaxy cluster formation, galaxy clustering, high-redshift star-forming galaxies, and dark matter.

Rafael Guzman specializes in galaxy evolution, with a special interest in luminous compact blue galaxies and dwarf elliptical galaxies. He is a member of the HST ACS Coma Treasury Survey, the AEGIS collaboration, and the GOYA survey.

Vicki Sarajedini conducts research related to AGN. Specific interests include as well AGN variability and dust and gas properties around quasars.
