Observation of Gravitational Waves from the Coalescence of a Compact Object and a Neutron Star

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1793

We report the observation of a coalescing compact binary with component masses and (all measurements quoted at the 90% credible le…

Search for continuous gravitational waves from known pulsars in the first part of the fourth LIGO-Virgo-KAGRA observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1816

Continuous gravitational waves (CWs) emission from neutron stars carries information about their internal structure and equation of state, and it can provide tests of General Relat…

Deep Search for Joint Sources of Gravitational Waves and High-Energy Neutrinos with IceCube During the Third Observing Run of LIGO and Virgo

The IceCube Collaboration, R. Abbasi, M. Ackermann +2209

The discovery of joint sources of high-energy neutrinos and gravitational waves has been a primary target for the LIGO, Virgo, KAGRA, and IceCube observatories. The joint detection…

A search using GEO600 for gravitational waves coincident with fast radio bursts from SGR 1935+2154

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1780

The magnetar SGR 1935+2154 is the only known Galactic source of fast radio bursts (FRBs). FRBs from SGR 1935+2154 were first detected by CHIME/FRB and STARE2 in 2020 April, after t…
