Adaptive mesh refinement in binary black holes simulations
Alireza Rashti, Maitraya Bhattacharyya, David Radice +3
We discuss refinement criteria for the Berger-Rigoutsos (block-based) refinement algorithm in our numerical relativity code GR-Athena++ in the context of binary black hole merger s…
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…
