Transient continuous gravitational wave searches using machine learning and the Hough transform
Andrew Miller (UCLouvain & Virgo)

We present two new methods to search for gravitational waves from isolated neutron stars lasting O(hours-days), and the results of two searches of real LIGO/Virgo data for a remnant of the first binary neutron star merger GW170817. One method looks for signals that follow a specific power-law model; the other uses convolutional neural networks to detect signals that deviate from this model. No significant candidates were found in either search, therefore we place upper limits on the possible gravitational wave emission from the remnant.
