Eccentric binary black holes: A new framework for numerical relativity waveform surrogates
Peter James Nee, Adhrit Ravichandran, Scott E. Field +17
Mounting evidence indicates that some of the gravitational wave signals observed by the LIGO/Virgo/KAGRA observatories might arise from eccentric compact object binaries, increasin…

Defining eccentricity for spin-precessing binaries
Md Arif Shaikh, Vijay Varma, Antoni Ramos-Buades +4
Standardizing the definition of eccentricity is necessary for unambiguous inference of the orbital eccentricity of compact binaries from gravitational wave observations. In previou…

A comparison between best-fit eccentricity definitions and the standardized definition of eccentricity
Nicolas Chartier, Md Arif Shaikh, Hyung Mok Lee +1
In the absence of a unique, gauge-independent definition of eccentricity in General Relativity, there have been efforts to standardize the definition for Gravitational-Wave astrono…
