  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.
