Impact of neglecting center-of-mass acceleration in parameter estimation of stellar-mass black holes
Suvikranth Gera, Poulami Dutta Roy
A tertiary body near a coalescing binary can imprint its influence on the gravitational waves (GWs) emitted by that binary in the form of center-of-mass (CoM) acceleration. An exam…

Shadows of generalised Hayward spacetimes : in vacuum and with plasma
Suvikranth Gera, Saurabh Kumar, Poulami Dutta Roy +1
We investigate the shadow properties of a wide class of spacetimes arising from different parameter regimes of the generalized Hayward metric, characterized by two independent para…

Black holes in degenerate Einstein Gauss-Bonnet gravity: Can QNMs distinguish them from GR?
Suvikranth Gera, Poulami Dutta Roy
In this study, for the first time, we analyse the quasinormal modes of black holes occurring within the framework of degenerate gravity. We investigate the properties of the asympt…
