Gravitational Waves from Inspiralling compact binaries: Modelling and implications

K G Arun

Compact binaries consisting of neutron stars and/or black holes are the most promising sources of gravitational waves for the existing ground based as well as planned space based interferometers. Matched filtering, a method which exploits the prior knowledge of the expected waveforms from these sources, will be employed for the data analysis of these signals. Thus it is very important to model the waveforms from these systems with the maximum possible accuracy. I will discuss one such important aspect, the so called `amplitude corrected post-Newtonian waveforms'. Implications of including these features in matched filtering will be discussed in the context of astrophysics, cosmology and testing general relativity.
