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…
