Supermassive Black Hole Science with the Legacy Survey of Space and Time

This is a recording of a talk titled "Supermassive Black Hole Science with the Legacy Survey of Space and Time" prepared for the "Spectral/Timing/Polarimetry Properties of AGN: Theory and Observations of the Inner Workings in these Objects" Scientific Event as part of COSPAR 2022 Assembly (2022 July; talk presented remotely). The speaker is Prof. W.N. Brandt from the Department of Astronomy & Astrophysics at the Pennsylvania State University. The talk has been prepared in collaboration with members of the LSST Active Galactic Nuclei Science Collaboration.
Here is the relevant abstract: The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will enable studies of the growing supermassive black holes (SMBHs) in active galactic nuclei (AGNs) on a truly massive scale. After a brief review of the LSST from an AGN perspective, I will describe the planned selection of tens of millions of AGNs, reaching to z = 7.5 and beyond, using the LSST plus multiwavelength data. I will then briefly highlight examples of exciting relevant LSST science investigations including massive AGN variability studies, transient SMBH fueling events, and high-redshift AGNs. I will end by describing the LSST AGN Science Collaboration (AGN SC), currently composed of about 120 members spanning the globe. The AGN SC aims to lead many of the AGN investigations and is preparing for AGN science with the petabyte deluge of LSST data.
