Active Galaxy Host Properties from a New H I 21-cm Survey of the Swift BAT-detected AGN
Abstract
Many questions remain open on how central supermassive black holes and their host galaxies form and affect each other's evolution. In order to answer these questions, we need to understand the observational properties of a complete sample of active galaxies. To this end, we have been collecting and studying multi-wavelength spectroscopy of a unique sample of active galaxies selected in the very hard X-rays with the Swift Burst Alert Telescope. Here we present an analysis of the 21-cm H I spectra, which we observed with the 100-m Green Bank Telescope in 2012, for a sample of 95 Swift-detected AGN. With this complete sample, we show evidence for differences in the host cold gas mass content between obscured and unobscured AGN.
