Constraints on coasting cosmological models from gravitational-wave standard sirens
Peter Raffai, Mária Pálfi, Gergely Dálya +1
We present the first test of coasting cosmological models with gravitational-wave standard sirens observed in the first three observing runs of the LIGO-Virgo-KAGRA detector networ…
Joint cosmological and gravitational-wave population inference using dark sirens and galaxy catalogues
Rachel Gray, Freija Beirnaert, Christos Karathanasis +11
In the absence of numerous gravitational-wave detections with confirmed electromagnetic counterparts, the "dark siren" method has emerged as a leading technique of gravitational-wa…
ICAROGW: A python package for inference of astrophysical population properties of noisy, heterogeneous and incomplete observations
Simone Mastrogiovanni, Grégoire Pierra, Stéphane Perriès +6
We present icarogw 2.0, a pure CPU/GPU python code developed to infer astrophysical and cosmological population properties of noisy, heterogeneous, and incomplete observations. ica…
A novel approach to infer population and cosmological properties with gravitational waves standard sirens and galaxy surveys
Simone Mastrogiovanni, Danny Laghi, Rachel Gray +7
Gravitational wave (GW) sources at cosmological distances can be used to probe the expansion rate of the Universe. GWs directly provide a distance estimation of the source but no d…
Impact of modelling galaxy redshift uncertainties on the gravitational-wave dark standard siren measurement of the Hubble constant
Cezary Turski, Maciej Bilicki, Gergely Dálya +2
Gravitational wave science is a new and rapidly expanding field of observational astronomy. Multimessenger observations of the binary neutron star merger GW170817 have provided som…
