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…
Two-dimensional gravity from vanishing metrical dimensions
Suvikranth Gera, Sandipan Sengupta
We obtain a dynamical formulation of two-dimensional gravity from a non-Einsteinian phase in higher dimensions . The formalism is associated with (at least) one extra dim…
Finite model of an electric charge
Suvikranth Gera, Sandipan Sengupta
We set up a model of an electric charge where the noninvertible metric phase of first order gravity supercedes the point charge singularity in a curved spacetime. A topological int…
Magnetic monopole as a spacetime defect
Suvikranth Gera, Sandipan Sengupta
We propose that the only possible realization of a magnetic pole is emergent, it being an artefact of a torsion defect in a curved spacetime. This special phase is characterized by…
Taming Dirac strings and timelike loops in vacuum gravity
Suvikranth Gera, Sandipan Sengupta
The problem of singularities associated with Dirac strings and closed timelike curves in classical solutions of pure gravity is analyzed here. A method to eliminate these is introd…
