Updated Upper Limits on the Isotropic Gravitational-Wave Background from LIGO, Virgo, and KAGRA Data through April 2025
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1805
We report results from a search for an isotropic stochastic gravitational-wave background using data collected by the LIGO--Virgo--KAGRA Collaboration. The analysis uses data from…
Constraints on ultralight bosons from merging binary and remnant black holes observed during the second and third parts of the fourth LIGO-Virgo-KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1808
We present constraints on ultralight bosons using binary black hole mergers observed in the second and third parts of the fourth LIGO-Virgo-KAGRA observing run. Directed searches a…
Advanced Virgo during the LIGO-Virgo-KAGRA fourth observing run
Virgo Collaboration, F Acernese, A Agapito +546
The paper reports on Advanced Virgo's participation in the fourth observing run (O4) of the global gravitational‑wave detector network, describing the commissioning of its new sign…
The ultra-fast afterglow of GRB 260226A
Biswajit Banerjee, Alessio Mei, Annarita Ierardi +13
The paper presents Fermi LAT observations of GRB 260226A that captured an unprecedented number of >100 MeV photons, enabling a detailed reconstruction of the early afterglow which…
GWTC-5.0: Tests of General Relativity
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1822
The signals from the LIGO-Virgo-KAGRA network of gravitational-wave (GW) detectors allow us to perform sensitive tests of general relativity (GR) in the dynamical and strong-field…
Detectability of Gravitational-wave counterparts of EP-FXTs observed during the O4b LIGO-Virgo-KAGRA Observing Run
Ansh Chopra, Samuele Ronchini, Biswajit Banerjee +5
Fast X-ray transients (FXTs) detected by the Einstein Probe mission have emerged as a rapidly growing class of extragalactic transients, whose physical origin remains uncertain. Co…
