Absorption cross section of RN and SdS extremal black hole
Sini R, Nijo Varghese, V C Kuriakose
The nature of scalar wave functions near the horizon of Reissner Nordstrom (RN) extremal and Schwarzschild-de Sitter (SdS) extremal black holes are found using WKB approximation an…

Massive Charged Scalar Quasinormal Modes of Reissner-Nördstrom Black Hole Surrounded by Quintessence
Nijo Varghese, V. C. Kuriakose
We evaluate the complex frequencies of the normal modes for the massive charged scalar field perturbations around a Reissner-Nördstrom black hole surrounded by a static and spheric…

Quasi-normal modes of spherically symmetric black hole spacetimes with cosmic string in a Dirac field
Sini R, Nijo Varghese, V. C. Kuriakose
Dirac equation for a general black hole metric having a cosmic string is derived. The quasi-normal mode frequencies for Schwarzschild, RN extremal, SdS and near extremal SdS black…
