Cosmology from Synergies Between SKAO Surveys and Gravitational Wave Observations
Tessa Baker, Alberto Colombo, Steven Cunnington +11
Both radio surveys and gravitational wave observations have the potential to probe unprecedented volumes in the Universe with systematics independent of existing cosmological probe…
Cosmic Cartography II: completing galaxy catalogs for gravitational-wave cosmology
Konstantin Leyde, Tessa Baker, Wolfgang Enzi
The dark siren method exploits the complementarity between gravitational-wave binary coalescence signals and galaxy catalogs originating from the same regions of space. However, al…
A Bright Future? Prospects for Cosmological Tests of GR with Multimessenger Gravitational Wave Events
Elena Colangeli, Konstantin Leyde, Tessa Baker
Further bright sirens - gravitational wave events with electromagnetic counterparts - are keenly awaited, but proving elusive. The exceptional event GW170817 had a profound impact…
Blinded Mock Data Challenge for Gravitational-Wave Cosmology-I: Assessing the Robustness of Methods Using Binary Black Holes Mass Spectrum
Aman Agarwal, Ulyana Dupletsa, Konstantin Leyde +18
Gravitational Wave (GW) sources are standard sirens that provide an independent way to map the cosmic expansion history by combining with an independent redshift measurement either…
Cosmic Cartography: Bayesian reconstruction of the galaxy density informed by large-scale structure
Konstantin Leyde, Tessa Baker, Wolfgang Enzi
The dark sirens method combines gravitational waves and catalogs of galaxies to constrain the cosmological expansion history, merger rates and mass distributions of compact objects…
