Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies [PDF]

, 2013
Supermassive black holes (BHs) have been found in 85 galaxies by dynamical modeling of spatially resolved kinematics. The Hubble Space Telescope revolutionized BH research by advancing the subject from its proof-of-concept phase into quantitative studies

On D-Branes and Black Holes in Four Dimensions [PDF]

, 1996
We find extremal four dimensional black holes with finite area constructed entirely from intersecting D-branes. We argue that the microscopic degeneracy of these configurations agrees with the Bekenstein-Hawking entropy formula.

Statistical studies of Spinning Black-Hole Binaries

, 2010
We study the statistical distributions of the spins of generic black-hole binaries during the inspiral and merger, as well as the distributions of the remnant mass, spin, and recoil velocity.

Gravitational Collapse of Gravitational Waves in 3D Numerical Relativity [PDF]

, 1999
We demonstrate that evolutions of three-dimensional, strongly non-linear gravitational waves can be followed in numerical relativity, hence allowing many interesting studies of both fundamental and observational consequences.

On critical behaviour in gravitational collapse

, 1995
We give an approach to studying the critical behaviour that has been observed in numerical studies of gravitational collapse. These studies suggest, among other things, that black holes initially form with infinitesimal mass.

Rapid and Bright Stellar-mass Binary Black Hole Mergers in Active Galactic Nuclei [PDF]

, 2016
The Laser Interferometer Gravitational-Wave Observatory, LIGO, found direct evidence for double black hole binaries emitting gravitational waves. Galactic nuclei are expected to harbor the densest population of stellar-mass black holes.

Examining the barriers, facilitators and attitudes towards COVID-19 vaccine and public health measures for black communities in Canada: a qualitative study protocol

BMJ Open, 2022
Introduction Black communities claim the highest number of cases and deaths due to COVID-19 in Canada. Generating culturally/contextually appropriate public health measures and strategies for vaccine uptake in black communities within Canada can better ...

Black Holes in Higher Dimensions (Black Strings and Black Rings)

, 2013
The main focus of this session was the presentation of new higher-dimensional black hole solutions, including black rings, black strings, and multi black holes, and the study of their properties. Besides new asymptotically flat and locally asymptotically

Maximum Spin of Black Holes Driving Jets [PDF]

, 2009
Unbounded outflows in the form of highly collimated jets and broad winds appear to be a ubiquitous feature of accreting black hole systems. The most powerful jets are thought to derive a significant fraction, if not the majority, of their power from the ...
