First Detection of an Overmassive Black Hole Galaxy UHZ1: Evidence for Heavy Black Hole Seed Formation from Direct Collapse

open access: yesThe Astrophysical Journal Letters, 2023
The recent Chandra-JWST discovery of a quasar in the z ≈ 10.1 galaxy UHZ1 reveals that accreting supermassive black holes were already in place 470 million years after the Big Bang. The Chandra X-ray source detected in UHZ1 is a Compton-thick quasar with

Instability of charged anti-de Sitter black holes

open access: yesPhysics Letters B, 2016
We have studied the instability of charged anti-de Sitter black holes in four- or higher-dimensions under fragmentation. The unstable black holes under fragmentation can be broken into two black holes.

Investigating strong gravitational lensing effects by supermassive black holes with Horndeski gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We study gravitational lensing in strong-field limit by a static spherically symmetric black hole in quartic scalar field Horndeski gravity having additional hair parameter q, evading the no-hair theorem.

Maximal forces and thermodynamic quantities of specific black holes in modified theories of gravity

open access: yesNuclear Physics B, 2023
In this work, we explore the maximum force conjecture and thermal fluctuations for different black holes such as the brane-world black hole, de Rham-Gabadadze-Tolley black hole, Black-Bounce Reisner-Nordström black hole, and renormalization group ...

Black holes of dimensionally continued gravity coupled to Born–Infeld electromagnetic field

open access: yesPhysics Letters B, 2018
In this paper, for dimensionally continued gravity coupled to Born–Infeld electromagnetic field, we construct topological black holes in diverse dimensions and construct dyonic black holes in general even dimensions.

Do stringy corrections stabilize coloured black holes? [PDF]

open access: yes, 1999
We consider hairy black hole solutions of Einstein-Yang-Mills-Dilaton theory, coupled to a Gauss-Bonnet curvature term, and we study their stability under small, spacetime-dependent perturbations. We demonstrate that the stringy corrections do not remove
