Gravitational Waves from the Inspiral of Supermassive Black Holes in Galactic-scale Simulations

10 Dec 2019 Mannerkoski Matias Johansson Peter H. Pihajoki Pauli Rantala Antti Naab Thorsten

We study the orbital evolution and gravitational wave (GW) emission of supermassive black hole (SMBH) binaries formed in gas-free mergers of massive early-type galaxies using the hybrid tree-regularized N-body code KETJU. The evolution of the SMBHs and the surrounding galaxies is followed self-consistently from the large-scale merger down to the final few orbits before the black holes coalesce... (read more)
