How Low Can You Go: Constraining the Effects of Catalog Incompleteness on Dark Siren Cosmology
Madison VanWyngarden, Maya Fishbach, Aditya Vijaykumar +2
Gravitational waves (GWs) serve as standard sirens by directly encoding the luminosity distance to their source. When the host galaxy redshift is known, for example, through observ…
Direct multi-model dark-matter search with gravitational-wave interferometers using data from the first part of the fourth LIGO-Virgo-KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1767
We search data from the first part of the fourth observing run of LIGO--Virgo--KAGRA for three kinds of dark matter -- dilatons (spin-0), dark photons (spin-1) and tensor bosons (s…
GWTC-4.0: Constraints on the Cosmic Expansion Rate and Modified Gravitational-wave Propagation
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
We analyze data from 142 of the 218 gravitational-wave (GW) sources in the fourth LIGO-Virgo-KAGRA Collaboration (LVK) Gravitational-Wave Transient Catalog (GWTC-4.0) to estimate t…
Spinning spectral sirens: Robust cosmological measurement using mass-spin correlations in the binary black hole population
Hui Tong, Maya Fishbach, Eric Thrane
Gravitational waves from compact binary mergers provide a direct measurement of luminosity distance, which, in combination with redshift information, serves as a cosmological probe…
Gravitational-wave dark siren cosmology systematics from galaxy weighting
Alexandra G. Hanselman, Aditya Vijaykumar, Maya Fishbach +1
The detection of GW170817 and the measurement of its redshift from the associated electromagnetic counterpart provided the first gravitational wave determination of the Hubble cons…
Ultralight vector dark matter search using data from the KAGRA O3GK run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1800
Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating l…
