Narrowband searches for continuous and long-duration transient gravitational waves from known pulsars in the LIGO-Virgo third observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1658
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully-coherent s…
Population inference of spin-induced quadrupole moments as a probe for non-black hole compact binaries
Muhammed Saleem, N. V. Krishnendu, Abhirup Ghosh +4
Gravitational-wave (GW) measurements of physical effects such as spin-induced quadrupole moments can distinguish binaries consisting of black holes from non-black hole binaries. Wh…
Search of the Early O3 LIGO Data for Continuous Gravitational Waves from the Cassiopeia A and Vela Jr. Supernova Remnants
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1411
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…
All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…
Constraining cosmological extra dimensions with gravitational wave standard sirens: from theory to current and future multi-messenger observations
Maxence Corman, Abhirup Ghosh, Celia Escamilla-Rivera +3
The propagation of gravitational waves (GWs) at cosmological distances offers a new way to test the gravitational interaction at the largest scales. Many modified theories of gravi…
Search for continuous gravitational waves from 20 accreting millisecond X-ray pulsars in O3 LIGO data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1634
Results are presented of searches for continuous gravitational waves from 20 accreting millisecond X-ray pulsars with accurately measured spin frequencies and orbital parameters, u…
