BLACK HOLE UNCERTAINTIES [PDF]
In this work the quantum theory of two-dimensional dilaton black holes is studied using the Wheeler-De Witt equation. The solutions correspond to wave functions of the black hole. It is found that for an observer inside the horizon, there are uncertainty relations for the black hole mass and a parameter in the metric determining the Hawking flux. Only

We consider the slowly rotating black hole with non-flat, non-(A)dS asymptotics and the rotating black holes with AdS asymptotics in the Einstein-Maxwell-dilaton (EMD) theory, and compare the shadows for such black holes with the Kerr-Newman-AdS black ...

Primordial Black Holes as a Dark Matter Candidate Are Severely Constrained by the Galactic Center 511 keV γ-Ray Line. [PDF]
We derive the strongest constraint on the fraction of dark matter that can be composed of low mass primordial black holes by using the observation of the Galactic Center 511 keV γ-ray line.

Cosmic conundra explained by thermal history and primordial black holes [PDF]
A universal mechanism may be responsible for several unresolved cosmic conundra. The sudden drop in the pressure of relativistic matter at $W^{\pm} / Z^{0}$ decoupling, the quark-hadron transition and $e^{+}e^{-}$ annihilation enhances the probability of

Information radiation in BCFT models of black holes [PDF]
In this note, following [1–3], we introduce and study various holographic systems which can describe evaporating black holes. The systems we consider are boundary conformal field theories for which the number of local degrees of freedom on the boundary ...

Macroscopic Black Holes, Microscopic Black Holes and Noncommutative Membrane
We study the stretched membrane of a black hole as consisting of a perfect fluid. We find that the pressure of this fluid is negative and the specific heat is negative too.

Universal thermodynamic topological classes of rotating black holes
In a recent study, Wei et al. (2024) [96] proposed a universal classification scheme that interprets black hole solutions, including the four-dimensional Schwarzschild, Reissner-Nordström (RN), Schwarzschild-AdS, and RN-AdS black hole solutions, as ...

Observing black holes spin [PDF]
The spin of a black hole retains the memory of how the black hole grew, and can be a potent source of energy for powering relativistic jets. To understand the diagnostic power and astrophysical significance of black hole spin, however, we must first ...
