With the observation of gravitational waves from merging compact binary systems, a new observing window of the universe has been opened. Most of the gravitational wave events currently
detected are due to the merger of binary black hole systems. One way to better investigate such
systems is to look for coincident emission in electromagnetic waves or neutrinos. For typical
models of isolated binaries, no such emission is expected. However, one promising class of
mergers is that of binary black holes in the accretion disk of active galactic nuclei. Such mergers
potentially occur at high rates, since these environments naturally have high numbers of black
holes, which can efficiently form binaries, merge rapidly, and potentially accrete matter fast due
to the surrounding gas. Here, we propose a method to search for coincident gravitational wave
and neutrino emission from the location of known AGN, using an unbinned maximum likelihood
analysis, and apply it to currently available public data.
