Prerequisites:

Basic knowledge of general relativity is suggested, but not mandatory. 
Target skills and knowledge:

Fundamentals of general relativity; linearized theory and gravitational waves (GW).
GW generation mechanisms and astrophysical sources.
Understanding of the working principles, main limitations and future prospects of GW detectors.
Elements of gravitational signal analysis.
Overview of the current state of the field of GW astronomy. 
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. 
Assessment criteria:

The students must demonstrate the comprehension and the ability to critically evaluate the concepts, mechanisms and problems related to the generation and detection of gravitational radiation. 
Course unit contents:

Elements of general relativity. Gravitational waves (GW) in linearized theory; TTgauge and detector frame; interaction with free falling masses and rigid bodies.
Generation of GW. Quadrupole and postnewtonian approximations. Energy and momentum loss by gravitational wave emission. Examples of GW sources: stable and coalescing binary systems, rotating rigid bodies, extreme massratio inspirals.
GW detection. HulseTaylor 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. 
Planned learning activities and teaching methods:

Frontal lessons with theory and examples 
Additional notes about suggested reading:

Lessons will be based on slides prepared by the teacher, which will be made available in advance to the students.
Excerpts from other written resources will be indicated as they become useful for specific sections of the course.
