Massive Black Hole Binary Evolution
Coalescence of binary supermassive black holes (SBHs) would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the separation between binary components first drop by a few orders of magnitude, due presumably to interactions of the binary with stars and gas in a g...
متن کاملThe evolution of massive black hole seeds
We investigate the evolution of high-redshift seed black hole masses at late times and their observational signatures. The massive black hole seeds studied here form at extremely high redshifts from the direct collapse of pre-galactic gas discs. Populating dark matter haloes with seeds formed in this way, we follow the mass assembly of these black holes to the present time using a Monte Carlo m...
متن کاملMassive Black Hole Growth and Formation
I review current difÞculties in understanding the origin of the supermassive black holes we now think reside in almost all normal to large galaxies. For example, it is not obvious how so much matter can be rapidly packed into such a small volume so as to produce the accreting supermassive black holes observed out to redshifts z > 6, when the Universe less than a tenth of its current age. I then...
متن کاملAstrophysics of super-massive black hole mergers
We present here an overview of recent work in the subject of astrophysical manifestations of super-massive black hole (SMBH) mergers. This is a field that has been traditionally driven by theoretical work, but in recent years has also generated a great deal of interest and excitement in the observational astronomy community. In particular, the electromagnetic (EM) counterparts to SMBH mergers p...
متن کاملThe Afterglow of Massive Black Hole Coalescence
The final merger of a pair of massive black holes in a galactic nucleus is compelled by gravitational radiation. Gravitational waves from the mergers of black holes of masses 105−7(1 + z)M⊙ at redshifts of 1 − 20 will be readily detectable by the Laser Interferometer Space Antenna (LISA), but an electromagnetic afterglow would be helpful in pinpointing the source and its redshift. Long before t...
