Black Hole Shadows of Charged Spinning Black Holes [PDF]
, 2005 We propose a method for measuring the black hole charge by imaging a black hole shadow in a galactic center by future interferometers. Even when the black hole is uncharged, it is possible to confirm the charge neutrality by this method. We first derive the analytic formulae of the black hole shadow in an optically thin medium around a charged spinning

Science Insights, 2019 The first picture of block hole was released on April 10th, 2019. This breakthrough came after a decade of collaborate work to align the myriad parts of the giant project and gain the highest resolution possible from the Earth’s surface. Even from our original consideration, block hole is a mysterious greedy hole that can suck anything away no matter ...

Physical Review D, 2018 In anticipation of a LIGO detection of a black hole/neutron star merger, we expand on the intriguing possibility of an electromagnetic counterpart. Black hole/Neutron star mergers could be disappointingly dark since most black holes will be large enough to swallow a neutron star whole, without tidal disruption and without the subsequent fireworks ...

Thermodynamic topology of topological charged dilatonic black holes
European Physical Journal C: Particles and FieldsThe aim of this paper is to explore the thermodynamic topology of topological charged dilatonic black holes. To achieve this, our study will begin by examining the characteristics of topological charged black holes in dilaton gravity.

(Anti-)Evaporation of Schwarzschild-de Sitter Black Holes
, 1997 We study the quantum evolution of black holes immersed in a de Sitter background space. For black holes whose size is comparable to that of the cosmological horizon, this process differs significantly from the evaporation of asymptotically flat black ...

Accretion, Primordial Black Holes and Standard Cosmology
, 2011 Primordial Black Holes evaporate due to Hawking radiation. We find that the evaporation time of primordial black holes increase when accretion of radiation is included.Thus depending on accretion efficiency more and more number of primordial black holes ...

Evolution of massive black holes [PDF]
arXiv, 2007 Supermassive black holes are nowadays believed to reside in most local galaxies. Accretion of gas and black hole mergers play a fundamental role in determining the two parameters defining a black hole: mass and spin. I briefly review here some of the physical processes that are conducive to the evolution of the massive black hole population.
