5. Continuous gravitational waves from unknown neutron stars in binary systems

Josep Blai Covas Vidal

Unknown neutron stars in binary systems might be one of the best sources of continuous gravitational waves (yet to be detected), due to their millisecond rotation rates, the accretion from their companion which can source the required asymmetry, and the vast unexplored parameter space. These searches have a prohibitive computational cost due to the large number of dimensions that need to be...

1. Deep Einstein@Home all-sky search for continuous gravitational waves in LIGO O3a public data

We present the results of the volunteer computing project Einstein@Home all-sky search for continuous gravitational waves in the LIGO O3 public data. This is the most sensitive search to date for the probed waveforms, with frequencies in the 20-800 Hz range and spin-downs between -2.6 x 10^-9 Hz s^-1 and 2.6 x 10^-10 Hz s^-1.

9. Not-so-blind searches for young, isolated, nearby gravitars

Blind searches for continuous gravitational-wave signals (CWs)
survey broad regions in the parameter-space in order to find
currently unknown sources with possibly no electromagnetic counterpart.
As a result, these searches are amongst the most computationally expensive
searches in the current gravitational-wave data-analysis landscape.
In this work, we revisit the detectability prospects...
