The Impact of Galaxy Catalogue Completeness with GLADE+ on Dark Siren Cosmology: A Line-of-Sight Prior Analysis of GWTC-3 Events
Juan Esteban Rivera, Antonio Enea Romano, Rachel Gray +2
Cosmological parameters can be estimated from dark sirens, gravitational waves events without electromagnetic counterpart, by using inference methods which estimate statistically t…
Expanding the scope of dark siren cosmology: Inferring the population properties of gravitational wave-hosting galaxies
Rachel Gray, Daniel Williams, Alexander Papadopoulos
The field of gravitational wave "dark siren" cosmology is facing a number of challenges surrounding the way in which galaxy catalogue data is incorporated into the analysis. The th…
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…
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…
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…
Testing the nature of gravitational wave propagation using dark sirens and galaxy catalogues
Anson Chen, Rachel Gray, Tessa Baker
The dark sirens method enables us to use gravitational wave events without electromagnetic counterparts as tools for cosmology and tests of gravity. Furthermore, the dark sirens an…
A Pixelated Approach to Galaxy Catalogue Incompleteness: Improving the Dark Siren Measurement of the Hubble Constant
Rachel Gray, Chris Messenger, John Veitch
The use of gravitational wave standard sirens for cosmological analyses is becoming well known, with particular interest in measuring the Hubble constant, , and in shedding li…
Cosmological Inference using Gravitational Wave Standard Sirens: A Mock Data Challenge
Rachel Gray, Ignacio Magaña Hernandez, Hong Qi +12
The observation of binary neutron star merger GW170817, along with its optical counterpart, provided the first constraint on the Hubble constant using gravitational wave stan…
