Studying Faint Ultra Hard X-ray Emission from AGN in GOALS LIRGs with Swift BAT
Michael Koss, Richard Mushotzky, Wayne Baumgartner +4
We present the first analysis of the all-sky Swift BAT ultra hard X-ray (14-195 keV) data for a targeted list of objects. We find the BAT data can be studied at 3x fainter limits t…
