Measurement of the Hubble constant using the Dark Energy Survey Year 6 Gold galaxy catalogue and the fourth Gravitational-Wave Transient Catalogue
Isaac McMahon, Danny Laghi, Marcelle Soares-Santos +9
Gravitational wave (GW) standard sirens enable independent measurements of the Hubble constant . In the absence of electromagnetic counterparts, the 'dark siren' method statis…
Scalable Dark Siren Cosmology with gwcosmo: GPU Acceleration, Validation and Systematics
Alexander Papadopoulos, Christian E. A. Chapman-Bird, Rachel Gray +2
As the number of confident gravitational-wave detections grows, population-level hierarchical analyses face increasing computational costs. Dark-siren cosmological inference integr…
The impact of strong lensing on Hubble constant measurements with gravitational-wave dark sirens
Eungwang Seo, Kyungmin Kim, Zhuotao Li +3
The disagreement between early and late Universe electromagnetic measurements of the Hubble constant, , known as the Hubble tension, highlights the need for independent and co…
Using gravitational wave dark sirens to choose between host galaxy weighting models
Zhuotao Li, Rachel Gray, Ik Siong Heng
Binary black hole (BBH) mergers,, an important source of gravitational-waves(GWs), are assumed to be hosted in galaxies. The probability of a galaxy to host a BBH is related to its…
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…
