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 Einstein potential in the same dimension. It is therefore expected that the energetics of a pure GB black hole would be weaker, and our analysis bears out that the efficiency of energy extraction by the Penroseprocess is increased to 25.8 % and the particle acceleration is increased to 55.28 %; the… 

Shadows of Kerr-like black holes in a modified gravity theory

In this paper, the shadows cast by non-rotating and rotating modified gravity black holes are investigated. In addition to the black hole spin parameter a and the inclination angle θ of observer,

Magnetized and Magnetically Charged Particles Motion around Regular Bardeen Black Hole in 4D Einstein Gauss–Bonnet Gravity

In this paper, we study the horizon properties and scalar invariants of the spacetime around a regular black hole (BH) in 4D Einstein Gauss-Bonnet (4D EGB) gravity. It is observed that the presence

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

Optical and thermodynamic properties of a rotating dyonic black hole spacetime in $${\mathcal {N}} = 2, U(1)^2$$ gauged supergravity

The null geodesics and the distance of closest approach for photon around a rotating dyonic black hole in N = 2, U(1) gauged supergravity is studied. The phenomenon of black hole shadows with various

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

Shadow of Non-singular Rotating Magnetic Monopole in Perfect Fluid Dark matter

Bardeen proposed a gravitationally collapsing magnetic monopole black hole solution that is free of singularity. In this article, we have studied the size and shape of the rotating Bardeen black hole



Particle and light motion in a space-time of a five-dimensional rotating black hole

We study motion of particles and light in a space-time of a 5-dimensional rotating black hole. We demonstrate that the Myers-Perry metric describing such a black hole in addition to three Killing

Shadow of rotating non-Kerr black hole

The shadow of a rotating non-Kerr black hole has been studied, and it was shown that in addition to the specific angular momentum a, the deformation parameter of non-Kerr spacetime essentially

Shadow of a rotating braneworld black hole

We investigate the shadow cast by a rotating braneworld black hole, in the Randall-Sundrum scenario. In addition to the angular momentum, the tidal charge term deforms the shape of the shadow. For a

Null geodesics and shadow of a rotating black hole in extended Chern-Simons modified gravity

The Chern-Simons modification to general relativity in four dimensions consists of adding to the Einstein-Hilbert term a scalar field that couples to the first-class Pontryagin density. In this


Recent general relativistic magnetohydrodynamics (MHD) simulations have suggested that relativistic jets from active galactic nuclei (AGNs) have been powered by the rotational energy of central black

Shadow of five-dimensional rotating Myers-Perry black hole

A black hole casts a shadow as an optical appearance because of its strong gravitational field. We study the shadow cast by the five-dimensional Myers-Perry black hole with equal rotation parameters.

Kerr black holes as particle accelerators to arbitrarily high energy.

We show that intermediate mass black holes conjectured to be the early precursors of supermassive black holes and surrounded by relic cold dark matter density spikes can act as particle accelerators

On the Gauss-Bonnet Gravity

We argue that propagation of gravitational field in the extra dimension is motivated by physical realization of second iteration of self interaction of gravity and it is described by the Gauss-Bonnet

Revival of the Penrose process for astrophysical applications

By utilizing the curious existence of negative energy orbits outside the event horizon of the Kerr black hole, Penrose proposed that rotational energy of the black hole can be extracted. It was
