Luminous Infrared Galaxies, Gas Flows and the Role of Mergers

Jeff Rich gives a seminar on Luminous Infrared Galaxies, Gas Flows and the Role of Mergers

Luminous Infrared Galaxies are some of the brightest and most active galaxies in the Universe.  The enormous amounts of infrared light given off by these systems is driven by huge bouts of star formation and by gas accretion onto supermassive black holes. In the nearby Universe, the physical process driving the intense physical conditions is often a merger of two massive spiral galaxies, ultimately resulting in a final coalesced system which has exhausted the fuel needed to sustain its activity. Large surveys taken in the X-Ray, UV, visible, infrared and radio are being used to study these systems and investigate how they relate to the history of star formation and galaxy evolution throughout cosmic time. I will present my observational research studies of Luminous Infrared Galaxies in the nearby Universe and discuss what these galaxies can tell us about the processes that govern a galaxy's life.
