Spin-induced Quadrupole Moment (SIQM) Test for Eccentric Compact Binaries
Syed U. Naqvi, Chandra Kant Mishra
The paper extends the spin‑induced quadrupole moment test of the no‑hair conjecture to eccentric compact binaries, using Fisher matrix forecasts to show that third‑generation detec…
Biased parameter inference of eccentric, spin-precessing binary black holes
Divyajyoti, Isobel M. Romero-Shaw, Vaishak Prasad +8
While the majority of gravitational wave (GW) events observed by the LIGO and Virgo detectors are consistent with mergers of binary black holes (BBHs) on quasi-circular orbits, som…
Testing the Kerr hypothesis beyond the quadrupole with GW241011
Rimo Das, N. V. Krishnendu, M. Saleem +2
All multipole moments of a Kerr black hole are uniquely determined by its mass and spin. Gravitational wave observations can test this prediction by measuring spin-induced multipol…
An Accurate Modeling of Nano-hertz Gravitational Wave Signal from Eccentric Supermassive Binary Black Holes: An Essential Step Toward a Robust Discovery
Mohit Raj Sah, Akash Maurya, Suvodip Mukherjee +7
The stochastic gravitational wave background (SGWB) in the nanohertz (nHz) regime, detectable by pulsar timing arrays (PTAs), provides a promising probe of the cosmic population of…
Chase Orbits, not Time: A Scalable Paradigm for Long-Duration Eccentric Gravitational-Wave Surrogates
Akash Maurya, Prayush Kumar, Scott E. Field +6
Orbital eccentricity is a key tracer of the astrophysical origins of compact binaries. Yet it remains absent from routine LIGO-Virgo-KAGRA analyses, in part because of the prohibit…
Inferring additional physics through unmodelled signal reconstructions
Rimo Das, V. Gayathri, Divyajyoti +4
Parameter estimation of gravitational wave data is often computationally expensive, requiring simplifying assumptions such as circularisation of binary orbits. Although, if include…
