On the search for intermediate duration gravitational waves using the spherical harmonic basis
The main focus of the work described here within, is the development of an analysis pipeline that can detect gravitational waves transients that have a duration from a large fraction of a second up to 100 seconds. Firstly, we will present the basic theory of gravitational waves, their generation and...
