Computing EM signatures from astrophysical compact binary mergers

In the next few years the new generation of gravitational wave detectors will likely detect some of the most energetics events in the universe; the coalescence and merger of binary compact objects, which will help to test gravity in the strong field regime. If the magnetic field is sufficiently strong, the binary may produce a detectable electromagnetic burst, especially if it is in the form of a jet. The concurrent detection of EM and GW signals (and possibly neutrinos) will open the door to the so-called multimessenger astronomy, which can confirm the detection and give more insight into the physical processes involved. I will describe some of the numerical evolutions involving black holes and neutron stars binaries, focusing on the GW waveforms, the possible EM counterparts and its astrophysical implications.
