Static Blackhole with Cosmological Influence: Whittaker Solutions
Santanu Tripathy, K Rajesh Nayak
In this article, we investigate the impact of cosmological parameters on black holes using an exact solution to Einstein's equations that satisfies the Whittaker equation of state.…
Swarm-intelligent search for gravitational waves from eccentric binary mergers
Souradeep Pal, K Rajesh Nayak
We implement an eccentric search for compact binary mergers based on particle swarm optimization. Orbital eccentricity is an invaluable input for understanding the formation scenar…
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…
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…
An Implementation of DF-GHG with Application to Spherical Black Hole Excision
Maitraya K Bhattacharyya, David Hilditch, K Rajesh Nayak +3
We present an implementation of the dual foliation generalized harmonic gauge (DF-GHG) formulation within the pseudospectral code bamps. The formalism promises to give greater free…
Analytical and numerical treatment of perturbed black holes in horizon-penetrating coordinates
Maitraya K Bhattacharyya, David Hilditch, K Rajesh Nayak +2
The deviations of non-linear perturbations of black holes from the linear case are important in the context of ringdown signals with large signal-to-noise ratio. To facilitate a co…
