Luis Lehner (Perimeter Institute, Waterloo, Canada).This workshop is a satellite event of Cosmo22 that will take place in Rio de Janeiro from August 22-26, 2022. Posters will be displayed during coffee breaks and flash presentations are planned, where each poster presenter will have 1′ to advertise their poster in front of the full audience. In addition to the invited talks, there will be space for contributed talks and posters. The aim of this workshop is to further stimulate activities in the Latin-American community in these rapidly evolving research areas related to classical gravity, to strengthen and spur new connections and collaborations, and to award the 20 ICTP-SAIFR Prizes for the best Latin-American thesis in Classical Gravity and Applications. The high level of coordination required to maximize the (astro)physics output of forthcoming observations makes it timely to explore the cross-correlation among these different probes of astronomy, cosmology and fundamental gravity.

New observations of transients of electromagnetic, cosmic rays and neutrino origin are expected in the next decade, which will serve as cosmological probes as well as cosmic laboratories of strong gravity and high-energy physics. Fundamental gravity, astronomy and cosmology have experienced unprecedented new developments and Gravitational Waves is a relatively recent actor on the stage.
