Strong Gravitational Lensing by Lorentzian-Euclidean Black Hole
Rukkiyya V. P, Shubham Kala, Sini R
We investigate the strong gravitational lensing properties of the Lorentzian Euclidean black hole, a spacetime in which the horizon at is not a coordinate singularity but a…
Quasinormal modes of RN black hole space time with cosmic string in a Dirac field
Sini R, V. C. Kuriakose
We evaluate quasinormal mode frequencies for RN black hole space times with cosmic string perturbed by a massless Dirac field, using Pöschl-Teller potential method. We find that on…
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…
Absorption cross section of RN black hole
Sini R., V. C. Kuriakose
The behavior of a charged scalar field in the RN black hole space time is studied using WKB approximation. In the present work it is assumed that matter waves can get reflected fro…
