European Physical Journal C: Particles and Fields, 2019 We study some physical properties of black holes in Null Aether Theory (NAT) – a vector-tensor theory of gravity. We first review the black hole solutions in NAT and then derive the first law of black hole thermodynamics.

Physical Review D, 1991 A renormalizable theory of quantum gravity coupled to a dilaton and conformal matter in two space-time dimensions is analyzed. The theory is shown to be exactly solvable classically.

Primordial black holes as a dark matter candidate [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2020 The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in Primordial Black Holes (PBHs) as a dark matter candidate.

Proceedings of the National Academy of Sciences, 2001 Recent progress in black hole research is illustrated by three examples. We discuss the observational challenges that were met to show that a supermassive black hole exists at the center of our galaxy. Stellar-size black holes have been studied in x-ray binaries and microquasars.

Dirty Black Holes and Hairy Black Holes [PDF]
Physical Review Letters, 1996 An approach based on considerations of the non-classical energy momentum tensor outside the event horizon of a black hole provides additional physical insight into the nature of discrete quantum hair on black holes and its effect on black hole temperature. Our analysis both extends previous work based on the Euclidean action techniques, and corrects an

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

Gravitational waves from a universe filled with primordial black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Ultra-light primordial black holes, with masses m PBH < 109g, evaporate before big-bang nucleosynthesis and can therefore not be directly constrained. They can however be so abundant that they dominate the universe content for a transient period (before ...

Two populations of LIGO-Virgo black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a hypothesis that the data contains more than one population of black holes.

A Fundamental Relation between Supermassive Black Holes and Their Host Galaxies [PDF]
, 2000 The masses of supermassive black holes correlate almost perfectly with the velocity dispersions of their host bulges, Mbh ∝ σα, where α = 4.8 ± 0.5. The relation is much tighter than the relation between Mbh and bulge luminosity, with a scatter no larger
