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

Elena Colangeli, Konstantin Leyde, Tessa Baker +1

Cosmological tests of general relativity (GR) using gravitational waves (GWs) often rely on parametrised forms of the luminosity distance-redshift ($d_{\mathrm{L}}-z$) relation, whic…
