Reconsidering the role of bright and dark gravitational-wave standard sirens for cosmology
Alberto Colombo, Sonia Triscari-Benimavò, Simone Mastrogiovanni
Gravitational-wave (GW) standard sirens have emerged as powerful probes of cosmic expansion. They are commonly divided into two classes: bright sirens, observed in coincidence with…
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…
Non-Parametric Reconstruction of the Hubble Parameter from the Fourth Gravitational Wave Transient Catalog and DESI Baryonic Acoustic Oscillations
Grégoire Pierra, Alberto Colombo, Simone Mastrogiovanni
The release of the fourth Gravitational Wave Transient Catalog (GWTC-4.0) by the LIGO-Virgo-KAGRA collaboration includes more than 200 compact binary coalescence (CBC) candidates t…
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…
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…
Constraints on the cosmic expansion history from GWTC-3
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1676
We use 47 gravitational-wave sources from the Third LIGO-Virgo-KAGRA Gravitational-Wave Transient Catalog (GWTC-3) to estimate the Hubble parameter , including its current va…
Search for subsolar-mass binaries in the first half of Advanced LIGO and Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 and 1.0 in Advanced LIGO and Advanced Virgo dat…
Constraints on dark photon dark matter using data from LIGO's and Virgo's third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present a search for dark photon dark matter that could couple to gravitational-wave interferometers using data from Advanced LIGO and Virgo's third observing run. To perform th…
