"Efficient technique to probe Stochastic Gravitational Wave Background Anisotropy with ground-based detectors"
Superposition of sources too weak to be detected individually is expected to create a persistent background. Different types of astrophysical and cosmological sources are likely to be present in this stochastic gravitational wave background, where the astrophysical background created by the nearby universe is expected to be anisotropic. We have developed efficient techniques based on data folding to efficiently search for anisotropic stochastic backgrounds using the standard gravitational wave radiometer algorithm, which will be summarised in this presentation. I will also discuss how sky maps are produced from the folded data using PyStoch code which can rapidly followup the outliers and help the blind all-sky all-frequency narrowband searches.
