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…
