DOI: 10.1007/jhep11(2019)042
Abstract: Abstract We study non-linearly the gravitational instabilities of the Reissner- Nordstrom-de Sitter and the Gauss-Bonnet-de Sitter black holes by using the large D expansion method. In both cases, the thresholds of the instability are found… read more here.

DOI: 10.1103/physrevd.100.124001
Abstract: We investigate the instability of the unstable circular orbit of a charged null particle to test the strong cosmic censorship conjecture in the near-extremal Reissner-Nordstrom-de Sitter black hole. The instability is estimated as the Lyapunov… read more here.

DOI: 10.1103/physrevd.98.125013
Abstract: Creation of thermal distribution of particles by a black hole is independent of the detail of gravitational collapse, making the construction of the eternal horizons suffice to address the problem in asymptotically flat spacetimes. For… read more here.

DOI: 10.1103/physrevd.99.024030
Abstract: We study the greybody factor and power spectra of Hawking radiation for the minimally or nonminimally coupled scalar field with exact numerical method in spherically symmetric Einstein-Gauss-Bonnet-de Sitter black hole spacetime. The effects of scalar… read more here.

DOI: 10.1142/s0217732320501400
Abstract: We investigate the cosmic censorship hypothesis for the Reissner–Nordström anti-de-Sitter black holes with global monopole charge. Considering the motion of the particle, we find that the overcharging is possible only for the anti-de-Sitter black hole… read more here.
