This federal Project Grant award of $140,000.00, provided by the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program, supports a research project led by the Regents of the University of Minnesota to search for and detect the stochastic gravitational wave background using data from Advanced LIGO, Advanced Virgo, and KAGRA gravitational wave detectors.
The project aims to characterize the composition of the stochastic gravitational wave background and identify implications for different astrophysical and cosmological models. It will leverage two search techniques - a traditional cross-correlation based search expected to be 10-40 times more sensitive than previous results, and a full Bayesian search for binary black hole mergers with potential 1000-fold sensitivity improvement. The research will offer opportunities for graduate and undergraduate student involvement, and support outreach activities to engage broader public communities. The award period runs from August 1, 2024 to July 31, 2027.
