Astrophysics Research Group

The Creighton astrophysics research group focuses on observational-based studies of active galactic nuclei (AGN), also known as quasars.  AGN are the energetic cores of galaxies that are emitting tremendous amounts of radiation over a broad range of the electromagnetic spectrum, powered by the accretion of matter into supermassive blackholes.  The group's current research involves studies of high velocity, energetic mass outflows that are observed in some AGN. They seek to understand the source and energetics of these AGN winds and to assess their role in blackhole-galaxy interactions and the evolutionary sequence of AGNs.  The primary tools used for their research are UV, optical, and Infrared spectra obtained with the Hubble Space Telescope, NASA’s Spitzer Space Telescope, and large ground based telescopes.
