Supermassive Black Hole Studies with the Legacy Survey of Space and Time: 2021 - Part 4 of 6

This is a recording of a meeting titled "Supermassive Black Hole Studies with the Legacy Survey of Space and Time: 2021" held remotely over Zoom on 2021 July 12-14. The meeting was organized by the Rubin Observatory Legacy Survey of Space and Time (LSST) Active Galactic Nuclei (AGN) Science Collaboration. The organizers were Roberto J. Assef (Universidad Diego Portales; Chile), W. Niel Brandt (Penn State University; USA), Luka C. Popovic (Astronomical Observatory, Belgrade; Serbia), and Gordon Richards (Drexel University; USA). There are four talks in this recorded part with talk titles and speakers as follows: "Searching for periodic quasars in time-domain surveys" - Yu-Ching Chen (UIUC) "Interpreting the Characteristic Timescale in AGN Light Curves: Implications for Rubin Observatory" - Colin J. Burke (UIUC) "Searching for changing-state AGNs in massive datasets with anomaly detection" - Paula Sanchez Saez (Millennium Inst of Astrophys / Inria Chile) "ZTF constraints on variability from intermediate-mass black hole candidates" - Ernesto Camacho-Iniguez (Inst of Astrophys - Pont Univ Catolica de Chile) The final approximately 45 minutes of the recording is a general discussion session for the results of the day. Please refer to the other parts for the other talks. Each talk is about 25-30 min long including time for questions/discussion.
