Abstract: M04.00003 : Detecting a stochastic gravitational-wave background with LIGO-Virgo-Kagra*
11:57 AM–12:33 PM
LIGO, Virgo, Kagra
In this talk, I will start by describing the sources and signals contributing to the GWB, putting them in perspective within the context of astrophysics and cosmology. I will then introduce the stochastic GW analysis methods we routinely employ within the Laser Interferometer Gravitational-wave Observatory (LIGO), Virgo, and Kagra (LVK) collaboration to search for GWBs, and present recent search results. These include upper limits on a number of different target signals from both stochastic and continuous wave searches. I will finally present forecasts for when and how we expect to detect a GWB from BBHs and BNSs with the LVK detectors.
