Black Hole Thermodynamics without a Black Hole? [PDF]
Nuclear Physics B, 2003 In the present paper we consider, using our earlier results, the process of quantum gravitational collapse and argue that there exists the final quantum state when the collapse stops.

Rotating black hole in Rastall theory
European Physical Journal C: Particles and Fields, 2018 Rotating black hole solutions in theories of modified gravity are important as they offer an arena to test these theories through astrophysical observation.

Bridging Scales in Black Hole Accretion and Feedback: Magnetized Bondi Accretion in 3D GRMHD
The Astrophysical Journal Letters, 2023 Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously challenging to simulate. We use a multi-zone computational method based on

Galaxies, 2023 In the past few years, the Event Horizon Telescope (EHT) has provided the first-ever event horizon-scale images of the supermassive black holes (BHs) M87* and Sagittarius A* (Sgr A*).

The effective action of superrotation modes
Journal of High Energy Physics, 2021 Starting from an analysis of four-dimensional asymptotically flat gravity in first order formulation, we show that superrotation reparametrization modes are governed by an Alekseev-Shatashvili action on the celestial sphere.

Extreme Tidal Stripping May Explain the Overmassive Black Hole in Leo I: A Proof of Concept
The Astrophysical Journal Letters, 2023 A recent study found dynamical evidence of a supermassive black hole of ∼3 × 10 ^6 M _⊙ at the center of Leo I, the most distant dwarf spheroidal galaxy of the Milky Way. This black hole, comparable in mass to the Milky Way’s Sgr A*, places the system >2

Galaxies, 2022 Tidal disruption events (TDEs) around supermassive black holes (SMBHs) are a potential laboratory to study super-Eddington accretion disks and sometimes result in powerful jets or outflows which may shine in the radio and sub-millimeter bands.

Accretion and Evaporation of Modified Hayward Black Hole [PDF]
, 2015 First we have assumed the most general static spherically symmetric black hole metric. The accretion of any general kind of fluid flow around the black hole have been investigated.
