This is the website of the Gravitational Wave Research Group at The Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, India. Here you will find descriptions of a variety of research and outreach activities pursued by a dozen or so researchers, which include students, postdocs, and faculty.
:: Synopsis of Gravitational Wave Research ::
Gravitational waves will not only allow us to test the predictions of General Relativity in regions of strong gravity, but will also serve as a tool to expand our understanding of the Universe. Direct observations of gravitational waves are being pursued by an international network of advanced (second generation) laser interferometric detectors. Presently a significant amount of effort is being devoted by this research community in developing algorithms and data analysis pipelines to efficiently search for gravitational wave signals in noisy data. Compact binary coalescences are interesting as sources of gravitational waves because their rates are expected to be favorable and their phases can be modeled to a very high accuracy, so that matched filtering can be used to search for them.
Gravitational waves, however, can probe a much wider range of known and (so far) unknown sources, where the phase evolution in most of cases is unmodeled or ill-modeled. A Stochastic Gravitational Wave Background (SGWB) is one of such source, which can be created by overlapping GW signals from unresolved astrophysical sources in the nearby anisotropic universe. A weaker isotropic SGWB is also expected from GWs produced in the early universe. Gravitational wave researchers in IUCAA work on astrophysical and cosmological aspects of both types of sources and on devising methods for detecting them.
