A Semi-Coherent Search for Continuous Waves on Cas A and Vela Jr in the O3a Data Set

The LIGO-Virgo Collaboration (LVC) looks for gravitational waves originating from a broad spectrum of celestial sources. Included among these sources are rapidly spinning neutron stars exhibiting non-axisymmetric deformation, which produce long-lived, well-defined, and roughly monochromatic gravitational waves, or continuous waves. Various search methods are used by the LVC when looking for continuous waves based on what prior information is known about the source. Here we present the results of a Weave implementation of a semi-coherent templated search method using the F-statistic to look for continuous waves in data from the O3a run.
