First joint observation by the underground gravitational-wave detector KAGRA with GEO 600

H. Abe, F. Acernese, K. Ackley, R. X. Adhikari et autres

Abstract We report the results of the first joint observation of the KAGRA detector with GEO 600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser interferometer with 3 km arms, located in Kamioka, Gifu, Japan. GEO 600 is …

Search of the Early O3 LIGO Data for Continuous Gravitational Waves from the Cassiopeia A and Vela Jr. Supernova Remnants

The LIGO Scientific Collaboration, R. Abbott, T. D. Abbott, F. Acernese et autres

We present directed searches for continuous gravitational waves from the neutron stars in the Cassiopeia A (Cas A) and Vela Jr. supernova remnants. We carry out the searches in the LIGO data from the first six months of the third Advanced LIGO …

Directional limits on persistent gravitational waves using data from Advanced LIGO’s first two observing runs

B. P. Abbott, R. Abbott, T. D. Abbott, S. Abraham et autres

We perform an unmodeled search for persistent, directional gravitational wave (GW) sources using data from the first and second observing runs of Advanced LIGO. We do not find evidence for any GW signals. We place limits on the broadband GW flux emitted …

First low frequency all-sky search for continuous gravitational wave signals

J. Aasi, B. P. Abbott, R. Abbott, T. D. Abbott et autres

In this paper we present the results of the first low frequency all-sky search of continuous gravitational wave signals conducted on Virgo VSR2 and VSR4 data. The search covered the full sky, a frequency range between 20 and 128 Hz with a …

First all-sky search for continuous gravitational waves from unknown sources in binary systems

J. Aasi, B. P. Abbott, R. Abbott, T. D. Abbott et autres

We present the first results of an all-sky search for continuous gravitational waves from unknown spinning neutron stars in binary systems using LIGO and Virgo data. Using a specially developed analysis program, the TwoSpect algorithm, the search was carried out on data …
