Simulating the emission from shocked disks and black hole--neutron star mergers

Astrophysical systems that radiate strongly in both electromagnetic and gravitational wave bands are of particular interest for study since the combined information can provide access to a number of rich phenomena. We simulate the possible electromagnetic emission from two scenarios: a disk perturbed by a recoiling super-massive black hole and the post-merger remnant disk from a black hole--neutron star merger. We present radiation transfer results from several configurations of these systems using different radiation models.
