Supermassive black holes (SMBHs) at the centers of galaxies, which manifest as active galactic nuclei (AGNs) when accreting, are now known to be a fundamental component of galaxies and play an important role in their evolution. Detecting complete samples of AGNs and understanding their connection to the properties of the host galaxies in which they reside has therefore been an extremely important goal of extragalactic astronomy. Over the past several decades, it has become clear that a large fraction of AGNs are missed in optical surveys due either to obscuration of the central engine, or contamination of the optical emission lines from star formation in the host galaxy. This is a significant deficiency, because these elusive AGNs are often found in key phases of galaxy evolution, such as late stage galaxy mergers, when the black hole is expected to grow most rapidly, or in low mass and bulgeless galaxies, a galaxy population that may place important constraints on models of SMBH ‘seed’ formation and merger-free models to SMBH growth.
With the advent of new facilities such as JWST, ALMA, LSST, and WFIRST, along with rapidly advancing developments in numerical modeling and statistical techniques, new and more sophisticated means of finding and characterizing elusive AGNs are becoming available.
The aim of this conference is to bring together observers and theorists with multi-wavelength expertise to address the following key questions:
