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…

Eccentricity evolution consistency test to distinguish eccentric gravitational-wave signals from eccentricity mimickers
Sajad A. Bhat, Avinash Tiwari, Md Arif Shaikh +1
Eccentric compact binary coalescences (CBCs) are expected to be observed in current and future gravitational-wave (GW) detector networks. However, it has been recently pointed out…

Surrogate modeling of gravitational waves microlensed by spherically symmetric potentials
Uddeepta Deka, Gopalkrishna Prabhu, Md Arif Shaikh +3
The anticipated observation of the gravitational microlensing of gravitational waves (GWs) promises to shed light on a host of astrophysical and cosmological questions. However, ex…
