Constraints on Gravitational Waves from the 2024 Vela Pulsar Glitch

The LIGO Scientific Collaboration · the Virgo Collaboration · the KAGRA Collaboration · Abac, A. G. · y 196 más

Abstract Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, which are sudden frequency changes in a pulsar’s rotation. Such glitches could cause a variety of transient gravitational-wave signals. Here, we searc...
