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 () relation, whic…
CosmoPyro: Gradients for Gravitational-Wave Cosmology
Konstantin Leyde, Elena Colangeli
Gravitational-wave (GW) observations of stellar-mass compact binary coalescences directly measure the source luminosity distance. Combined with the source redshift, these measureme…
The impact of precession and higher-order multipoles for gravitational wave cosmological inference
Charlie Hoy, Konstantin Leyde
Gravitational-wave astronomy presents an exciting opportunity to provide an independent measurement of the expansion rate of the Universe. By combining inferences for the binary co…
Radio sirens: inferring with binary black holes and neutral hydrogen in the era of the Einstein Telescope and the SKA Observatory
Ulyana Dupletsa, Simone Mastrogiovanni, Marta Spinelli +11
A new synergy between gravitational waves (GWs) and the study of the large-scale structure of the Universe is now emerging. Along this line of research, we combine simulated observ…
End-to-End Population Inference from Gravitational-Wave Strain using Transformers
Konstantin Leyde, Stephen R. Green, Maximilian Dax +3
The population of compact binaries encodes information about their astrophysical origins and the expansion of the universe. Hierarchical Bayesian methods infer these properties by…
