Long-term evolution of massive black hole binaries. IV. Mergers of galaxies with collisionally relaxed nuclei
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We simulate mergers between galaxies containing collisionally-relaxed nuclei around massive black holes (MBHs). Our galaxies contain four mass groups, representative of old stellar populations; a prim...
Electromagnetic counterparts of supermassive black hole binaries resolved by pulsar timing arrays
black hole physics — gravitational waves — accretion, accretion discs— galaxies: active
2011/10/9
Pulsar timing arrays (PTAs) are expected to detect gravitational waves (GWs) from individual low-redshift (z<1.5) compact supermassive (M>10^9 Msun) black hole (SMBH) binaries with orbital periods of ...
