Analysis of late-time tails in spin-aligned eccentric binary black hole mergers
Tousif Islam, Guglielmo Faggioli, Gaurav Khanna
We present a comprehensive analysis of late-time tails in gravitational radiation from merging spin-aligned eccentric binary black holes, using high-accuracy point-particle black h…
Modeling the merger-ringdown of an eccentric test-mass inspiral into a Kerr black hole using the effective-one-body framework
Guglielmo Faggioli, Alessandra Buonanno, Maarten van de Meent +1
We characterize and phenomenologically model the merger-ringdown of gravitational waves emitted by a small compact object that plunges and merges into a Kerr black hole from equato…
Advancing the Effective-One-Body Framework in the Test-Mass Limit
Nami Nishimura, Alessandra Buonanno, Guglielmo Faggioli +2
We present SEOB-TML, an enhanced effective-one-body (EOB) framework for the test-mass limit, optimized for quasi-circular, spin-aligned binary black holes. On the dynamical side, w…
Phenomenology and origin of late-time tails in eccentric binary black hole mergers
Tousif Islam, Guglielmo Faggioli, Gaurav Khanna +3
We investigate the late-time tail behavior in gravitational waves from merging eccentric binary black holes (BBH) using black hole perturbation theory. For simplicity, we focus onl…
Peaking into the abyss: Characterizing the merger of equatorial-eccentric-geodesic plunges in rotating black holes
Guglielmo Faggioli, Maarten van de Meent, Alessandra Buonanno +1
We study the gravitational waveforms generated by critical, equatorial plunging geodesics of the Kerr metric that start from an unstable-circular-orbit, which describe the test-mas…
Variations in Relevance Judgments and the Shelf Life of Test Collections
Andrew Parry, Maik Fröbe, Harrisen Scells +5
The fundamental property of Cranfield-style evaluations, that system rankings are stable even when assessors disagree on individual relevance decisions, was validated on traditiona…
