Cosmological Inference with Gravitational-Wave Dark Sirens and 21-cm Intensity Mapping: Forecasts for LIGO-Virgo-KAGRA with MeerKAT and SKAO
Dounia Nanadoumgar-Lacroze, Konstantin Leyde, Steven Cunnington +8
Gravitational waves (GWs) and 21-cm intensity mapping (IM) are emerging as complementary cosmological probes: GWs provide direct luminosity-distance measurements, while neutral-hyd…
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…
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…
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…
Gravitational wave populations and cosmology with neural posterior estimation
Konstantin Leyde, Stephen R. Green, Alexandre Toubiana +1
We apply neural posterior estimation for fast-and-accurate hierarchical Bayesian inference of gravitational wave populations. We use a normalizing flow to estimate directly the pop…
Transverse Doppler effect and parameter estimation of LISA three-body systems
Adrien Kuntz, Konstantin Leyde
Some binary black hole systems potentially observable in LISA could be in orbit around a supermassive black hole (SMBH). The imprint of relativistic three-body effects on the wavef…
