Gravitational wave memory and geodesic congruence response in generalised Ellis-Bronnikov wormholes
Soumya Bhattacharya, Suman Ghosh
We investigate gravitational wave memory in generalised Ellis-Bronnikov wormhole spacetimes by studying the response of neighbouring timelike geodesics and geodesic congruences to…

Ratio of two independent xgamma random variables and some distributional properties
Subhradev Sen, Suman K. Ghosh, Hazem Al-Mofleh
In this investigation, the distribution of the ratio of two independently distributed xgamma (Sen et al. 2016) random variables X and Y , with different parameters, is proposed and…

Signature quasinormal modes of Ellis-Bronnikov wormhole embedded in warped braneworld background
Antariksha Mitra, Suman Ghosh
We examine the quasi normal modes of Ellis-Bronnikov wormholes embedded in a warped five dimensional braneworld background and compare with it's four dimensional counterpart. These…
