Abstract
We use the Kepler Space Telescope to search for Active Galactic Nuclei (AGNs). We lookthrough 105 nearby galaxies and, using a customized pipeline, find two objects which demon- strate aperiodic variability typical of AGNs. One object, KIC 8093535, is a well-known X-ray source, giving us confidence that this is in fact an AGN. Using a damped random walk, we model our two objects and find that the stochastic variability is AGN-like. We also use the damping timescale to model the AGN central black-hole masses of our objects and find that both nuclei are in the upper Intermediate Mass Black Hole /lower Super Massive Black Hole regime.
