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…

Directed searches for gravitational waves from ultralight vector boson clouds around merger remnant and galactic black holes during the first part of the fourth LIGO-Virgo-KAGRA observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1769

We present the first directed searches for long-transient and continuous gravitational waves from ultralight vector boson clouds around known black holes (BHs). We use LIGO data fr…

GWTC-4.0: Searches for Gravitational-Wave Lensing Signatures

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1766

Gravitational waves can be gravitationally lensed by massive objects along their path. Depending on the lens mass and the lens--source geometry, this can lead to the observation of…
