Continuous waves and stochastic signals
Invited talk
The recent sensitivity improvements of the worldwide advanced gravitational-wave detector network has allowed us to detect the first transient gravitational-wave signal, marking thus the official beginning of the gravitational-wave astronomy. We have then started to hone the comprehension of some of the objects populating our Universe. A broader picture would be however provided by the...

Observations by Advanced LIGO and Advanced Virgo in the coming years will allow for important limits to be set on on the strength of a stochastic gravitational-wave background; a detection may happen as well. Sources for the stochastic gravitational-wave background could be cosmologically or astrophysically produced. The implications of the recent observations of GW150914 and GW151226 indicate...

Rapidly rotating neutron stars are promising sources of continuous gravitational waves for the LIGO and Virgo interferometers. All-sky searches for isolated neutron stars offer the potential to detect gravitational waves from neutron stars that have not been observed electromagnetically. The broad parameter space of these all-sky searches presents a significant computational challenge. The...

Disturbed neutron stars -- soon after their birth, after a starquake or due to episodic accretion -- could emit gravitational waves in the ground-based detector band, both in the form of initial bursts and as longer-lasting weak transients. Data analysis methods derived from the established search efforts for "continuous waves" are well suited for transient quasi-periodic signals with...

The low-mass X-ray binary Scorpius X-1 is a promising source of continuous gravitational waves. Its high X-ray luminosity indicates a large rate of accretion, which may power GW emission. A variety of methods have been developed and applied to search for the signal, which presents challenges because of the unknown signal frequency and residual uncertainties in orbital parameters. I will...
