No nonminimally coupled massless scalar hair for spherically symmetric neutral black holes

We provide a remarkably compact proof that spherically symmetric neutral black holes cannot support static nonminimally coupled massless scalar fields. Expand abstract.

Testing Horndeski Theory Using Light Deflection by Asymptotically Flat Black Holes

We also examine the graphical impact of deflection angle on asymptotically flat black holes in the background of Horndeski theory in plasma as well as non-plasma medium. Expand abstract.

Finite-Distance Gravitational Deflection of Massive Particles by the Kerr-like Black Hole in the Bumblebee Gravity Model

In this paper, we study the weak gravitational deflection angle of relativistic massive particles by the Kerr-like black hole in the bumblebee gravity model. Expand abstract.

Modeling bias in supermassive black hole spin measurements

X-ray reflection spectroscopy (or iron line method) is a powerful tool to probe the strong gravity region of black holes, and currently is the only technique for measuring the spin of supermassive black holes. Expand abstract.

Strong Cosmic Censorship for a Scalar Field in a Logarithmic-de Sitter Black Hole

Relevant issues for Reissner-Nordstrom-de Sitter (RNdS) black holes and Born-Infeld-de Sitter (BI-dS) black holes have been discussed. Expand abstract.

Probing holography in $p$-adic CFT

We holographically calculate the partition functions of CFTs dual to Bruhat-Tits trees and $p$-adic BTZ black holes. Expand abstract.

Non-thermal aspects of Unruh effect

Although black holes are the best arena to explore this interplay, evidences for their existence are lacking, suggesting to address less exotic contexts. Expand abstract.

Black holes, Planckian granularity, and the changing cosmological `constant'

In a recent work we have argued that nosy energy momentum diffusion due to space-time discreteness at the Planck scale (naturally expected to arise from quantum gravity) can be responsible for the generation of a cosmological constant during the electro-weak phase transition era of the cosmic evolution.

Unitarity from a smooth horizon?

Under semiclassical evolution, black holes retain a smooth horizon but fail to return information. Expand abstract.
