Theoretical Light Curve Modeling and Follow-Up Observations of Binary Black Hole Mergers in AGN Disks — •Julian Sommer1, Daniel Grün1 und Antonella Palmese2 — 1Ludwig-Maximilians-Universität München, München, Deutschland — 2Carnegie Mellon University, Pittsburgh, USA
Black holes with masses ranging from several dozen to hundreds of solar masses are primarily believed to exist in the regions of active galactic nuclei, specifically within the accretion disks of supermassive black holes. The interaction of the merger remnant with the surrounding gas can lead to electromagnetic signatures that can be identified in their light curves. The duration of such a signature can extend from days to months and can be described as a light curve. In this talk, we present initial results from the theoretical modeling of such light curves and compare them with our observations to analyze the relationship between theory and practice. Our follow-up observation campaigns of gravitational wave detections by LIGO/Virgo/KAGRA are conducted using the 2.1-meter Wendelstein telescope, which is equipped with both the 3KK imager and the Wide-Field Imager.
