Astrophysical Signatures of Black Hole Mergers (speaker: Manuela Campanelli, Rochester Institute of Technology)
Numerical relativity simulations of binary black hole inspirals and mergers played a crucial role in the calculations of the gravitational wave signals that were just observed by the advanced LIGO and Virgo detectors. For supermassive binary black holes, these signals might also be accompanied by observable electromagnetic signals from surrounding accreting gas. I will briefly review the history of simulation efforts to model these systems in their astrophysical environments. I will also present some exciting new results in the context of magnetohydrodynamical simulation, indicating that supermassive binary black hole sources might indeed be also detectable in the electromagnetic spectrum in the not too distant future.
