The Seventeenth Marcel Grossmann Meeting: On Recent Developments In Theoretical And Experimental General Relativity, Astrophysics, And Relativistic Field Theories (In 3 Volumes)

The proceedings contain the results presented at the Seventeenth Marcel Grossman meeting, giving a broad view of all aspects of gravitational physics and astrophysics, from mathematical issues to recent observations and experiments. The scientific program of the meeting included 41 plenary presentations, 3 public lectures and 62 parallel sessions arranged during the intense five-day meeting. All talks, including two lectures of Nobel Laureates Roger Penrose and Reinhard Genzel were streamed and are available on the ICRANet YouTube channel at the following link: https://n9.cl/cjkafn.These proceedings are a representative sample of the very many contributions made at the meeting. They contain about 200 papers, among which 14 come from the plenary sessions.The material represented in these proceedings cover the following topics: accretion, artificial intelligence methods, alternative theories of gravity, black holes (classical and beyond), compact objects and stellar evolution, cosmic microwave background and cosmological tensions, cosmic rays and very high energy emission, dark energy and large scale structure, dark matter, early universe, experimental gravitation, fast radio bursts, gamma-ray bursts, gravitational waves, high energy, high-precision astrometry, history of relativity, multimessenger astrophysics, neutrinos, quantum gravity, strong fields, theory and experiments in fundamental physics and X-ray polarization; all of them represented by a large number of contributions.
