The discovery in the early 1970s that black holes radiate as black bodies has radically
affected our understanding of general relativity, and offered us some early hints about the …

Lanczos–Lovelock models of gravity represent a natural and elegant generalization of
Einstein's theory of gravity to higher dimensions. They are characterized by the fact that the …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

This chapter reviews standard tools used in the analysis of horizon and black hole physics,
most notably the congruences of null geodesics crossing a horizon. Rindler, event, Killing …

The Rényi and Tsallis entropies are discussed as possible alternatives to the Bekenstein-
Hawking area-law entropy. It is pointed out how replacing the entropy notion, but not the …

We investigate the Hawking radiation of massive spin-1 vector particles, which are coupled
to vacuum fluctuations of a quantum field, from a Rindler modified Schwarzschild black hole …

In this work, we present the inverted harmonic oscillator (IHO) Hamiltonian as a paradigm to
understand the quantum mechanics of scattering and time-decay in a diverse set of physical …

The effect of Lorentz symmetry breaking (LSB) on the Hawking radiation of Schwarzschild-
like black hole found in the bumblebee gravity model (SBHBGM) is studied in the framework …

A short review of spherically symmetric static regular black holes and spherically symmetric
non-singular cosmological space-time is presented. Several models, including new ones, of …

A toy model of Einstein gravity with a Gauss-Bonnet classically “entropic” term mimicking a
quantum correction is considered. The static black hole solution due to Tomozawa is found …
