The BAT AGN Spectroscopic Survey (BASS) Second Data Release
Abstract
The Burst Alert Telescope (BAT) instrument on the Swift satellite has surveyed the sky to unprecedented depth, increasing the all sky hard X-ray sensitivity by a factor of more than 20 compared to previous satellites. The goal of the BAT AGN Spectroscopic Survey (BASS) is to complete the first large (>1000) survey of hard X-ray selected AGN with optical spectroscopy. This work will place constraints on the growth and structure around nearby black holes and provide a baseline for future European X-ray missions, such as ATHENA, that will perform deeper observations of more distant AGN. Here we present an overview of the 11 recent papers published by our collaboration using the first data release and an overview of the second data release which includes redshift determination, absorption and emission line measurements, and black hole mass and accretion rate estimates via broad lines and velocity dispersion for over 1000 AGN.
