Quest for CMB spectral distortions to probe the scalar-induced gravitational wave background interpretation of pulsar timing array data
Matteo Tagliazucchi, Matteo Braglia, Fabio Finelli +1
Gravitational Waves (GW) sourced by second-order primordial curvature fluctuations are among the favored models fitting the recent pulsar timing array (PTA) measurement of a stocha…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Probing Early Modification of Gravity with Planck, ACT and SPT
Guillermo Franco Abellán, Matteo Braglia, Mario Ballardini +2
We consider a model of early modified gravity (EMG) that was recently proposed as a candidate to resolve the Hubble tension. The model consists in a scalar field with a non-min…
Stochastic gravitational wave background constraints from Gaia DR3 astrometry
Santiago Jaraba, Juan García-Bellido, Sachiko Kuroyanagi +2
Astrometric surveys can be used to constrain the stochastic gravitational wave background (SGWB) at very low frequencies. We use proper motion data provided by Gaia DR3 to fit a ge…
Open data from the third observing run of LIGO, Virgo, KAGRA and GEO
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1741
The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data…
