Wide parameter-space O3 search for continuous gravitational waves from unknown neutron stars in binary systems
P. B. Covas, M. A. Papa, R. Prix
Continuous gravitational waves, i.e., persistent and nearly-monochromatic signals emitted by asymmetric spinning neutron stars, remain elusive. Searches for these signals from unkn…
Bayesian Framework to Follow-up Continuous Gravitational Wave Candidates from Deep Surveys
Jasper Martins, Maria Alessandra Papa, Benjamin Steltner +2
Broad all-sky searches for continuous gravitational waves have high computational costs and require hierarchical pipelines. The sensitivity of these approaches is set by the initia…
Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…
Generalized parameter-space metrics for continuous gravitational-wave searches
P. B. Covas, R. Prix
Many searches for continuous gravitational waves face significant computational challenges due to the need to explore large parameter spaces characterized by unknown parameters. Pa…
Search for continuous gravitational waves from unknown neutron stars in binary systems with long orbital periods in O3 data
P. B. Covas, M. A. Papa, R. Prix
Gravitational waves emitted by asymmetric rotating neutron stars are the primary targets of continuous gravitational-wave searches. Neutron stars in binary systems are particularly…
