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, dark matter, dark energy, and the CMB.

Faculty Research

Our extragalactic group focuses on a number of topics including Active Galactic Nuclei, Galaxy Formation and Evolution, Galaxy Structure, Galaxy Clusters, Galaxy Clustering, Dark Matter, Structure Formation, Observational Cosmology, Theoretical Cosmology, and 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.

Desika Narayanan's research focuses on theoretical models primarily related to cosmological galaxy evolution, star formation, and the interstellar medium (ISM). He develops and utilizes large scale numerical simulations to simulate the interplay between small scale star formation, ISM physics, and global galaxy evolution.

Zachary Slepian’s research follows three broad paths: creating theoretical models for large-scale structure, designing fast algorithms to measure it, and applying them to datasets such as BOSS, eBOSS, and DESI.

Paul Torrey conducts research in a wide range of topics in galaxy formation and evolution using numerical simulations. He is a core member of the Illustris collaboration and makes heavy use of the HiPerGator-2 HPC machine to develop and run next generation cosmological simulations.
