Viscous attenuation of gravitational waves propagating through an inhomogeneous background
Shashank Shekhar Pandey, Arnab Sarkar, Amna Ali +1
We consider the propagation of gravitational waves in the late-time Universe in the presence of matter distribution inhomogeneities, and we also consider the cosmic fluid to be vis…
Enhanced power of gravitational waves and rapid coalescence of black hole binaries through dark energy accretion
Arnab Sarkar, Amna Ali, K. Rajesh Nayak +1
We consider the accretion of dark energy by constituent black holes in binary formations during the present epoch of the Universe. In the context of an observationally consistent d…
Effect of inhomogeneities on the propagation of gravitational waves from binaries of compact objects
Shashank S. Pandey, Arnab Sarkar, Amna Ali +1
We consider the propagation of gravitational waves in the late time Universe with the presence of structure. Before detection, gravitational waves emitted from distant sources have…
Evolution of axial perturbations in space-time of a non-rotating uncharged primordial black hole
Arnab Sarkar, Sabiruddin Molla, K. Rajesh Nayak
We derive the equation governing the axial-perturbations in the space-time of a non-rotating uncharged primordial black hole (PBH), produced in early Universe, whose metric is take…
Perturbative correction terms to electromagnetic self-force due to metric perturbation : astrophysical and cosmological implications
Arnab Sarkar, Amna Ali, Salah Nasri
We consider the equation of motion of a charged particle or a charged compact object in curved space-time, under the reaction of electromagnetic radiation and also consider a physi…
