Syllabus
Prerequisites: General Relativity is recommended
Examination methods: Oral examination aimed at verifying the conceptual understanding of the topics presented and the ability to correctly approach and analyze specific problems related to GW theory and detection.
Course unit contents: Elements of general relativity. Gravitational waves (GW) in linearized theory; TT-gauge; interaction with matter.

Generation of GW. Quadrupole and post-newtonian approximations. Examples of GW sources: stable and coalescing binary systems, rotating rigid bodies, extreme mass-ratio inspirals.

GW detection. Hulse-Taylor system. Fundamentals of stochastic signals and noise theory. Resonant bars detectors. Modern GW interferometers: basic principle, noise sources, fundamental and technical limitations. Future GW experiments. Elements of data analysis.

Astronomy and science with gravitational waves. Current observations of black hole and neutron star mergers. Tests of general relativity. Astrophysical implications. Multimessenger astronomy.
