Black Holes, Mergers, and the Entropy Budget of the Universe [PDF]

JCAP 0311 (2003) 011, 2002
Vast amounts of entropy are produced in black hole formation, and the amount of entropy stored in supermassive black holes at the centers of galaxies is now much greater than the entropy free in the rest of the universe. Either mergers involved in forming supermassive black holes are rare,or the holes must be very efficient at capturing nearly all the ...

Mass Functions of Supermassive Black Holes Across Cosmic Time [PDF]

, 2011
The black hole mass function of supermassive black holes describes the evolution of the distribution of black hole mass. It is one of the primary empirical tools available for mapping the growth of supermassive black holes and for constraining theoretical models of their evolution.

Formation of Supermassive Black Holes [PDF]

The Astronomy and Astrophysics Review, 2010
Evidence shows that massive black holes reside in most local galaxies. Studies have also established a number of relations between the MBH mass and properties of the host galaxy such as bulge mass and velocity dispersion.

SuperMassive Black Holes in Bulges [PDF]

The Astrophysical Journal, 2000
We present spatially extended gas kinematics at parsec-scale resolution for the nuclear regions of four nearby disk galaxies, and model them as rotation of a gas disk in the joint potential of the stellar bulge and a putative central black hole.

Possible evidence for the ejection of a supermassive black hole from an ongoing merger of galaxies [PDF]

Mon.Not.Roy.Astron.Soc.Lett.366:L22-L25,2006, 2005
Attempts of Magain et al (2005) to detect the host galaxy of the bright QSO HE0450--2958 have not been successful. We suggest that the supermassive black hole powering the QSO was ejected from the observed ULIRG at the same redshift and at 1.5 arcsec distance.

Evolution of supermassive black holes [PDF]

, 2006
Supermassive black holes (SMBHs) are nowadays believed to reside in most local galaxies, and the available data show an empirical correlation between bulge luminosity - or stellar velocity dispersion - and black hole mass, suggesting a single mechanism ...

Measuring spin of a supermassive black hole at the Galactic centre -- Implications for a unique spin [PDF]

, 2009
We determine the spin of a supermassive black hole in the context of discseismology by comparing newly detected quasi-periodic oscillations (QPOs) of radio emission in the Galactic centre, Sagittarius A* (Sgr A*), as well as infrared and X-ray emissions with those of the Galactic black holes.

, 2004
A review of recent theoretical work on the interactions of supermassive single and binary black holes with their nuclear environments, highlighting ways in which the observed structure of nuclei can be used to constrain the formation history of black holes.

The Formation of Supermassive Black Holes and the Evolution of Supermassive Stars [PDF]

Class.Quant.Grav. 18 (2001) 3965-3976, 2000
The existence of supermassive black holes is supported by a growing body of observations. Supermassive black holes and their formation events are likely candidates for detection by proposed long-wavelength, space-based gravitational wave interferometers like LISA.
