One Year and One Night to 1% in : Efficient Spectroscopic Strategy for Dark Siren Cosmology
Yixuan Dang, Ariel J. Amsellem, Ignacio Magaña Hernandez +2
Gravitational-wave events from compact binary coalescences (CBCs) can be used as standard sirens: they encode the luminosity distance to their sources, which yields a measurement o…
Golden and Silver Dark Sirens for precise H0 measurement with HETDEX
Yixuan Dang, Ish Gupta, Robin Ciardullo +12
Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…
Are black hole spins truly near-zero?
Vaishak Prasad, B. S. Sathyaprakash
The fourth gravitational-wave transient catalog, GWTC-4.0, reports 153 binary black hole mergers with false-alarm rates . Chirp masses are typically measured w…
Confronting general relativity with principal component analysis: Simulations and results from GWTC-3 events
Parthapratim Mahapatra, Sayantani Datta, Ish Gupta +10
We present a comprehensive assessment of multiparameter tests of general relativity (GR) in the inspiral regime of compact binary coalescences using principal component analysis (P…
