Cosmological Inference with Gravitational-Wave Dark Sirens and 21-cm Intensity Mapping: Forecasts for LIGO-Virgo-KAGRA with MeerKAT and SKAO

Gravitational waves (GWs) and 21-cm intensity mapping (IM) are emerging as complementary cosmological probes: GWs provide direct luminosity-distance measurements, while neutral-hydrogen (HI) IM traces the matter distribution in redshift space. Their synergy offers a promising avenue for precise measurements of the Hubb...

No parametrisation, No Problem: A Weakly Modelled Framework to Constrain the Luminosity Distance--Redshift Relation Using Gravitational Wave Sirens

Cosmological tests of general relativity (GR) using gravitational waves (GWs) often rely on parametrised forms of the luminosity distance-redshift ($ d_{\rm L} - z$) relation, which is modified in alternative theories of gravity where the gravitational coupling strength is time-dependent. Although they can lead to stri...
