| Venue: | G02, Lecture Hall Complex |
| Details: | Gravitational waves are the prediction of Einstein's theory of relativity and other relativistic theories of gravity. Although their existence has been established by the observation of the orbital decay of the Hulse-Taylor binary pulsar, their detection with man made antennas has not been achieved. In this talk the global effort of the search for gravitational waves with laser interferometric observatories will be discussed. India's role in this worldwide search will be described. The sensitivity of detectors and possible astrophysical gravitational wave sources will be discussed. Briefly, the data analysis of extracting gravitational wave signals from by inspiraling binaries will be described. Next, the detection of stochastic gravitational waves with a directed search will be discussed in the context of the Virgo cluster which appears as a hot spot with implications to Olbers' paradox. |
