3d Summation-by-Parts scheme for Linear Wave Equations on Hyperboloidal Slices
Anuraag Reddy, Shalabh Gautam, Prayush Kumar
We derive a fully 3-dimensional Summation-By-Parts scheme for a class of linear wave equations on hyperboloidal slices that meet future null infinity on a Minkowski background. The…
Merger remnant and eccentricity dynamics surrogates for eccentric nonspinning black hole binaries
Adhrit Ravichandran, Peter James Nee, Keefe Mitman +22
Accurate models of merger remnants are increasingly important for gravitational-wave science, including precision tests of gravity with ringdown, inference of black-hole population…
Including higher-order modes in a quadrupolar eccentric numerical relativity surrogate using universal eccentric modulation functions
Tousif Islam, Adhrit Ravichandran, Peter James Nee +15
\texttt{gwNRHME} is a framework that converts multi-modal (i.e., containing several spherical harmonic modes) quasi-circular waveforms into their eccentric counterparts, provided t…
Rapid inference of gravitational-wave signals in the time domain using a heterodyned likelihood
Neha Sharma, Aditya Vijaykumar, Prayush Kumar
Parameter estimation of gravitational wave signals is computationally intensive and typically requires millions of likelihood evaluations to construct posterior probability distrib…
Dynamo and Jet interconnections in GRMHD simulations of black hole accretion disks
P. S. Santhiya, Pallavi Bhat, Prayush Kumar +2
We present global 3D GRMHD simulations of black hole (BH) accretion disks designed to investigate how MRI-driven dynamo action regulates jet formation and evolution. Unlike standar…
Gravitational Waves from Strongly Magnetized Eccentric Neutron Star Binaries
R. Prasad, Anushka Doke, Prayush Kumar
We explore the dynamics of neutron star binaries that approach their final inspiral stages with residual eccentricity and strong magnetic fields, features that can arise in systems…
Generalized Perturbed Kepler Problem: Gravitational Wave Imprints from Eccentric Compact Binaries
Rajes Ghosh, R. Prasad, Kabir Chakravarti +1
Observations of astrophysical binaries may reveal departures from pure Keplerian orbits due to environmental influences, modifications to the underlying gravitational dynamics, or…
Early Warning From Eccentric Compact Binaries: Template Initialization And Sub-dominant Mode Effects
Priyanka Sinha, R. Prasad, Mukesh Kumar Singh +3
Early warning of gravitational waves (GWs) is essential for multi-messenger observations of binary neutron star and black hole-neutron star merger events. In this study, we investi…
AI and extreme scale computing to learn and infer the physics of higher order gravitational wave modes of quasi-circular, spinning, non-precessing binary black hole mergers
Asad Khan, E. A. Huerta, Prayush Kumar
We use artificial intelligence (AI) to learn and infer the physics of higher order gravitational wave modes of quasi-circular, spinning, non precessing binary black hole mergers. W…
