A Possible Evolution of Black Holes by Using a Hydrodynamic Analogy [PDF]
INCAS Bulletin, 2023 The creation of black holes starts with the implosion of a star after the fuel to power the thermonuclear reactions from inside was consumed. Then more and more mass is added until a critical value of the ratio mass/radius was obtained.

Physical Review D, 2020 In this paper, we look for the vacuum static spherically symmetric solution in the mimetic gravity scenario based on the conformal invariance principle. The trivial solution is a stealth Schwarzschild black hole with scalar hair where the mimetic field does not contribute to the background. However, a solution with two naked singularities shows up when

QCD and spin effects in black hole airshowers [PDF]
, 2007 In models with large extra dimensions, black holes may be produced in high-energy particle collisions. We revisit the physics of black hole formation in extensive airshowers from ultrahigh-energy cosmic rays, focusing on collisional QCD and black hole ...

Journal of High Energy Physics, 2023 We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat, self-dual Kähler geometry known as Burns space.

Black-Hole Remnants from Black-Hole–Neutron-Star Mergers [PDF]
Physical Review Letters, 2019 Observations of gravitational waves and their electromagnetic counterparts may soon uncover the existence of coalescing compact binary systems formed by a stellar-mass black hole and a neutron star. These mergers result in a remnant black hole, possibly surrounded by an accretion disk.

Area Entropy and Quantized Mass of Black Holes from Information Theory
Entropy, 2021 In this paper, we present a derivation of the black hole area entropy with the relationship between entropy and information. The curved space of a black hole allows objects to be imaged in the same way as camera lenses.

Celestial amplitudes in an ambidextrous basis
Journal of High Energy Physics, 2023 We start by constructing a conformally covariant improvement of the celestial light transform which keeps track of the mixing between incoming and outgoing states under finite Lorentz transformations in ℝ2,2.
