Wheeler-DeWitt equation and the late gravitational collapse: effects of factor ordering and the tunneling scenario

Davide Batic, Marek Nowakowski, Neelima Govind Kelkar

We set up the Wheeler-DeWitt (WDW) equation for late gravitational collapse. The fact that the gravitational collapse and the expanding/ collapsing universe can be described within…

In-Stabilities of massive white dwarfs in modified gravity

Ronaldo V. Lobato, Geanderson A. Carvalho, Neelima G. Kelkar +1

Super-Chandrasekhar white dwarfs are a timely topic in the last years in the scientific community due to its connection to supernovae type Ia (SN Ia). Some early studies tackled th…

Massive white dwarfs in gravity

R. V. Lobato, G. A. Carvalho, N. G. Kelkar +1

In this work, we investigate the equilibrium configurations of massive white dwarfs (MWD) in the context of modified gravity, namely gravity, where stands for the Ri…

Perturbing microscopic black holes inspired by noncommutativity

Davide Batic, N. G. Kelkar, Marek Nowakowski +1

We probe into the instabilities of microscopic quantum black holes. For this purpose, we study the quasinormal modes (QNMs) for a massless scalar perturbation of the noncommutative…

Orbiting phenomena in black hole scattering

D. Batic, N. G. Kelkar, M. Nowakowski

Rainbow, glory and orbiting scattering are usually described by the properties of the classical deflection function related to the real part of the quantum mechanical scattering ph…

On Born approximation in black hole scattering

D. Batic, N. G. Kelkar, M. Nowakowski

A massless field propagating on spherically symmetric black hole metrics such as the Schwarzschild, Reissner-Nordström and Reissner-Nordström-de Sitter backgrounds is considered. I…
