Constraints on the Cosmological Coupling of Black Holes from the Globular Cluster NGC 3201
The Astrophysical Journal Letters, 2023 Globular clusters are among the oldest stellar populations in the Milky Way; consequently, they also host some of the oldest known stellar-mass black holes, providing insight into black hole formation and evolution in the early ( z ≳ 2) universe.

Gravitational anomalies: a recipe for Hawking radiation [PDF]
, 2008 We explore the method of Robinson and Wilczek for deriving the Hawking temperature of a black hole. In this method, the Hawking radiation restores general covariance in an effective theory of near-horizon physics which otherwise exhibits a gravitational ...

Galaxies, 2023 We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Towards a Full Quantum Theory of Black Holes [PDF]
, 1998 This review gives an introduction to various attempts to understand the quantum nature of black holes. The first part focuses on thermodynamics of black holes, Hawking radiation, and the interpretation of entropy.

Logarithmic corrections to entropy for black holes with hyperbolic horizon [PDF]
Class.Quant.Grav.26:065007,2009, 2008 We compute logarithmic corrections to entropy for black holes with hyperbolic horizon. For this purpose, we introduce the topological black hole and MTZ black holes in four dimensions, while in five dimensions, the topological black holes and Gauss-Bonnet black hole with negative coupling are considered.

Journal of High Energy Physics, 2018 We present novel asymptotically global AdS4 solutions, constructed by turning on a dipolar differential rotation at the conformal boundary. At fixed energy and boundary profile, we find two different geometries: a horizonless spacetime, and a deformed, hourglass shaped black hole with zero net angular momentum.

Thermodynamics of the Schwarzschild and the Reissner–Nordström black holes with quintessence
Nuclear Physics B, 2016 In this paper, we study the thermodynamics of the Schwarzschild and the Reissner–Nordström black holes surrounded by quintessence. By using the thermodynamical laws of the black holes, we derive the thermodynamic properties of these black holes and we ...
