Stable bound orbits around static Einstein-Gauss-Bonnet black holes

As is well-known, asymptotically flat, static and spherically symmetric black holes do not admit stable bound orbits of massive/massless particles outside the horizon in higher-dimensional Einstein

Weak cosmic censorship conjecture in the pure Lovelock gravity

It is well known that a rotating black hole in four dimension could be overspun by linear order test particle accretion which however always gets overturned when non-linear perturbations are

How do rotating black holes form in higher dimensions?

Black holes are generally formed by gravitational collapse and accretion process. The necessary condition for the process to work is that overall force on collapsing/accreting matter element must be

Charged black hole in 4D Einstein-Gauss-Bonnet gravity: particle motion, plasma effect on weak gravitational lensing and centre-of-mass energy

We study the motion of charged and spinning particles and photons in the 4D charged Einstein-Gauss-Bonnet (EGB) black hole vicinity. We determine the radius of the innermost stable circular orbit

Motion of charged and spinning particles influenced by dark matter field surrounding a charged dyonic black hole

We investigate the motion of massive charged and spinning test particles around a charged dyonic black hole surrounded by perfect fluid scalar dark matter field. We obtain the equations of motion and

Simple compactifications and black p-branes in Gauss-Bonnet and Lovelock theories

We look for the existence of asymptotically flat simple compactifications of the form D−p × Tp in D-dimensional gravity theories with higher powers of the curvature. Assuming the manifold D−p to be

Rotating black holes in 4D Einstein-Gauss-Bonnet gravity and its shadow

Recently there has been a surge of interest in regularizing, a D → 4 limit of, the Einstein-Gauss-Bonnet (EGB) gravity, and the resulting regularized 4D EGB gravity has nontrivial dynamics. The

Energetics and optical properties of 6-dimensional rotating black hole in pure Gauss–Bonnet gravity

We study physical processes around a rotating black hole in pure Gauss–Bonnet (GB) gravity. In pure GB gravity, the gravitational potential has a slower fall-off as compared to the corresponding

The higher dimensional Myers–Perry black hole with single rotation always obeys the cosmic censorship conjecture

Even though the Myers–Perry five dimensional rotating black hole with two rotations could be overspun by test particle accretion, yet it turns out as we show in this letter that it cannot do so for a

Five-dimensional charged rotating minimally gauged supergravity black hole cannot be over-spun and/or over-charged in non-linear accretion

Generally a black hole could be over-charged/spun, violating the weak cosmic censorship conjecture (WCCC) for linear order accretion while the same is always restored for non-linear accretion. The

A distinguishing gravitational property for gravitational equation in higher dimensions

It is well known that Einstein gravity is kinematic (meaning that there is no non-trivial vacuum solution; i.e. the Riemann tensor vanishes whenever the Ricci tensor does so) in 3 dimension because
