BLACK HOLE UNCERTAINTIES [PDF]
Modern Physics Letters A, 1993 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

Quantum-Gravity Fluctuations and the Black-Hole Temperature [PDF]
, 2015 Bekenstein has put forward the idea that, in a quantum theory of gravity, a black hole should have a discrete energy spectrum with concomitant discrete line emission.

Simulations of black hole air showers in cosmic ray detectors [PDF]
, 2005 We present a comprehensive study of TeV black hole events in Earth's atmosphere originated by cosmic rays of very high energy. An advanced fortran Monte Carlo code is developed and used to simulate black hole extensive air showers from ultrahigh-energy ...

European Physical Journal C: Particles and Fields, 2023 Stimulated by the recent researches of black hole thermodynamics for black hole with Newman–Unti–Tamburino (NUT) parameter, we investigate the thermodynamics and weak cosmic censorship conjecture for a Kerr–Newman Taub–NUT black hole.

Strong Gravitational Lensing by Kiselev Black Hole [PDF]
, 2015 We investigate the gravitational lensing scenario due to Schwarzschild-like black hole surrounded by quintessence (Kiselev black hole). We work for the special case of Kiselev black hole where we take the state parameter $w_{q}=-\frac{2}{3}$.

The center of mass energy of two colliding particles in the STU black holes
, 2013 In this paper we consider collision of two particle near the STU black hole and calculate center of mass energy. In the case of uncharged black hole we find that the maximum energy obtained near the black hole horizon which similarly happen for charged ...

The Redshift Evolution of the M •–M ⋆ Relation for JWST’s Supermassive Black Holes at z > 4
The Astrophysical JournalJWST has detected many overmassive galactic systems at z > 4, where the mass of the black hole, M _• , is 10–100 times larger than expected from local relations, given the host’s stellar mass, M _⋆ .

Black holes die hard: can one spin-up a black hole past extremality?
, 2010 A possible process to destroy a black hole consists on throwing point particles with sufficiently large angular momentum into the black hole. In the case of Kerr black holes, it was shown by Wald that particles with dangerously large angular momentum are
