Searches for Stochastic Gravitational Wave Background in LIGO Data

Incoherent superposition of gravitational waves (GWs) from a large number of unresolved sources is expected to give rise to a stochastic background of GWs. This stochastic gravitational wave background (SGWB) is one of the four types of GW signals LIGO is looking for. The SGWB could be either of astrophysical origin, produced by a large number of compact objects such as neutron stars, black holes etc., or of cosmological origin, produced in the early universe by events such as inflation. Detection of the stochastic gravitational wave background could provide information both about the state of the universe at its earliest moments and its evolution at later times. In this talk, I will discuss the results from searches for SGWB in LIGO data as well as results from a few other experiments.
