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

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.

Dilaton gravity approach to three dimensional Lifshitz black hole
, 2010 The z=3 Lifshitz black hole is an exact black hole solution to the new massive gravity in three dimensions. In order to understand this black hole clearly, we perform a dimensional reduction to two dimensional dilaton gravity by utilizing the circular ...

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.

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 _⋆ .

Quantum black hole–white hole entangled states
Physics Letters B, 2022 We investigate the quantum deformation of the Wheeler–DeWitt equation of a Schwarzchild black hole. Specifically, the quantum deformed black hole is a quantized model constructed from the quantum Heisenberg–Weyl Uq(h4) group.

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 ...
