The Measurement Problem in the Thermodynamics of Black Holes [PDF]

open access: yesEntropy
This manuscript gives a solution to the black hole information paradox by bringing to the debate a fundamental aspect of information science: the process of measurement by a receiver.

Quantum vortex instability and black hole superradiance

open access: yesPhysical Review Research, 2022
Vortices and black holes set the scene for many interesting dynamical processes in physics. Here, we study the dynamical instability of quantized vortices and rotational superradiance around rotating black holes, illustrating in the process that the same

A simple, approximate method for analysis of Kerr-Newman black hole dynamics and thermodynamics [PDF]

open access: yesSerbian Astronomical Journal, 2009
In this work we present a simple approximate method for analysis of the basic dynamical and thermodynamical characteristics of Kerr-Newman black hole.

Thermalization of horizon through asymptotic symmetry in three-dimensional massive gravity

open access: yesPhysics Letters B, 2021
Recently, black hole symmetries have been studied widely and it has been speculated that this procedure will lead to the deeper understanding of the black hole physics.

Bohr's Semiclassical Model of the Black Hole Thermodynamics [PDF]

open access: yesSerbian Astronomical Journal, 2008
We propose a simple procedure for evaluating the main attributes of a Schwarzschild's black hole: Bekenstein-Hawking entropy, Hawking temperature and Bekenstein's quantization of the surface area.

A Detailed View of Low-frequency Quasi-periodic Oscillation in the Broadband 0.2–200 keV with Insight-HXMT and NICER

open access: yesThe Astrophysical Journal, 2023
We report the X-ray timing results of the black hole candidate MAXI J1820+070 during its 2018 outburst using the Hard X-ray Modulation Telescope (Insight-HXMT) and Neutron Star Interior Composition Explorer Mission (NICER) observations.

UV–Optical Disk Reverberation Lags despite a Faint X-Ray Corona in the Active Galactic Nucleus Mrk 335

open access: yesThe Astrophysical Journal, 2023
 We present the first results from a 100-day Swift, NICER, and ground-based X-ray–UV–optical reverberation mapping campaign of the Narrow-line Seyfert 1 Mrk 335, when it was in an unprecedented low X-ray flux state.

Burns space and holography

open access: yesJournal 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.

Focus on classical and quantum analogues for gravitational phenomena and related effects [PDF]

open access: yes, 2012
Hawking's prediction that black holes are not black but radiate has been one of the intellectually most influential results of theoretical physics, but Hawking's theory has not so far been testable. Recent developments in analogue models of gravity might
