Tarnished by Tools: Cost of Systematics in Golden Dark Siren Cosmology

Giovanni Benetti, Koustav Chandra, Bangalore S. Sathyaprakash

Golden dark sirens - exceptionally well-localized gravitational-wave (GW) sources without electromagnetic counterparts - offer a powerful route to precision measurements of the Hub…

From Source Properties to Strong-Field Tests: a multipronged analysis of GW250114 with an effective one-body model for generic orbits

Koustav Chandra, Rossella Gamba, Danilo Chiaramello

We present a detailed analysis of GW250114, the loudest gravitational-wave signal observed to date, using a waveform model capable of describing binary black holes in generic (ecce…

Parametrized model for gravitational waves from eccentric, precessing binary black holes: theory-agnostic tests of General Relativity with pTEOBResumS

Danilo Chiaramello, Nicolò Cibrario, Jacob Lange +4

Gravitational waves from binary black hole mergers allow us to test General Relativity in the strong-field, high-curvature regime. However, existing gravitational waves-based tests…
