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.

Physical Review D, 1996 One would expect spacetime to have a foam-like structure on the Planck scale with a very high topology. If spacetime is simply connected (which is assumed in this paper), the non-trivial homology occurs in dimension two, and spacetime can be regarded as being essentially the topological sum of $S^2\times S^2$ and $K3$ bubbles.

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.

Kretschmann Scalar for a Kerr-Newman Black Hole [PDF]
, 1999 I have derived the Kretschmann scalar for a general black hole of mass m, angular momentum per unit mass a, and electric charge Q. The Kretschmann scalar gives the amount of curvature of spacetime, as a function of position near (and within) a black hole.

International Journal of Modern Physics D, 2003 Production of high-energy gravitational objects is a common feature of gravitational theories. The primordial universe is a natural setting for the creation of black holes and other nonperturbative gravitational entities. Cosmic black holes can be used to probe physical properties of the very early universe which would usually require the knowledge of

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 Thermodynamics and Two-Dimensional Dilaton Gravity Theory [PDF]
, 1999 We relate various black hole solutions in the near-horizon region to black hole solutions in two-dimensional dilaton gravity theories in order to argue that thermodynamics of black holes in D>=4 can be effectively described by thermodynamics of black ...

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.

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.
