Workshop on Relativistic Cosmology: Theoretical and Data Analysis Techniques An introductory workshop on Active Galactic Nuclei and Blazars was organized by the Presidency University, Kolkata during July 22 - 23, 2024. The workshop was a precursor to the " Blazars and Restless AGN': A High Energy View" conference held at Presidency University, Kolkata from July 24 - 26, 2024. The workshop was organized by the School of Astrophysics at the Presidency University, Kolkata and IUCAA, Pune. IUCAA provided financial support along with the Board of Research in Nuclear Sciences (BRNS). The workshop aimed at introducing the M.Sc, senior B.Sc students, and Ph.D scholars, primarily located in Kolkata, to the physics of active galactic nuclei (AGN) and related The workshop comprised day-long lectures with a 30-minute break between lectures. A set of multiple-choice-type questions were asked at the end of each lecture and the participants anonymously responded to those via a web page, which was set up by the organizers. The topics such as radiative processes, particle acceleration, accretion, observations & theoretical models of relativistic jets, astronomical detection of high energy photons and neutrinos, and potential career opportunities in Astronomy & Astrophysics. Fifty-five participants from various institutions took part in the workshop. distribution of answers given by the participants demonstrated that they had learned the topics well. A discussion was held at the last session of the workshop to r ece i ve f eedback abou t wha t t he participants found useful in the workshop and what changes they would have preferred. Later, the lecture material was shared and detailed online anonymous feedbackwas taken fromall participants. The resource persons were Vaidehi Paliya (IUCAA), Sunder Sahayanathan (BARC), Indranil Chattopadhyay (ARIES), and Debanjan Bose (Central University of Kashmir). Vaidehi Paliya (IUCAA) and Ritaban Chatterjee (Presidency University, Kolkata) coordinated theworkshop.
