Knowledge
The student will have acquired an up-to-date knowledge of physical phenomena involving the emission of gravitational radiation. He will be able to undestand the astrophysical implications of detecting various sorts of gravitational wave signals, in relation with the nature of the source, also in connection with sky observations in different bands of the electromagnetic spectrum (multimessenger astronomy). He will be able to perform simple general relativity calculations involving emission of gravitational waves.
The student will have also developed an understanding of gravitational wave detectors, interferometers in particular, their current performance in terms of noise, as well as their future development. He will have acquired the basic techniques for signal processing that are necessary to process gravitational wave signals.
