Chaotic Accretion and Merging Supermassive Black Holes
, 2012 The main driver of the work in this thesis is the idea of chaotic accretion in galaxy centres. Most research in this area focuses on orderly or coherent accretion where supermassive black holes or supermassive black hole binaries are fed with gas always ...

Two Radio Cores in GPS J1543-0757: A New Dual Supermassive Black Hole System?
The Astrophysical JournalWe report on the discovery of a dual supermassive black hole system in the radio galaxy J1543−0757, with a projected separation between the two black holes of ∼46 mas. The result is based on recent multifrequency observations using the Very Long Baseline

GalaxiesWe propose that modifications to the Higgs potential within a narrow atmospheric layer near the event horizon of an astrophysical black hole could significantly enhance the rate of sphaleron transitions, as well as transform the Chern–Simons number into ...

The Astrophysical JournalMany stellar-mass black holes (sBHs) are expected to orbit supermassive black holes at galactic centers. For galaxies with active galactic nuclei, it is likely that the sBHs reside in a disk.

Supermassive black holes with stellar companions
AIP Conference Proceedings, 1994 Low‐mass stars in close orbits around supermassive black holes in active galactic nuclei (AGN) may provide an important signature for testing the existence of supermassive black holes. Here we discuss how such systems can form by being ‘‘ground down’’ by their interaction with an AGN accretion disk and discuss the peculiarities of such binaries with ...

Accretion Into and Emission from Black Holes [PDF]
, 1976 Analyses are given of various processes involving matter falling into or coming out of black holes. A significant amount of matter may fall into a black hole in a galactic nucleus or in a binary system.

Uniqueness of near-horizon geometries of rotating extremal AdS(4) black holes [PDF]
, 2009 We consider stationary extremal black hole solutions of the Einstein-Maxwell equations with a negative cosmological constant in four dimensions. We determine all non-static axisymmetric near-horizon geometries and all static near-horizon geometries for ...

A Comparison of the X-Ray Polarimetric Properties of Stellar and Supermassive Black Holes
The Astrophysical JournalX-ray polarization provides a new way to probe accretion geometry in black hole systems. If the accretion geometry of black holes is similar regardless of mass, we should expect the same to be true of their polarization properties.
