The topics are organized around three main domains:
AGN cycle and galaxy clusters : feedback from AGNs, UFO, extragalactic cosmic rays, galaxy clusters and related AGN physics, HITOMI/XRISM and Athena sciences
Multi-messenger astrophysics : GRB host galaxies, UHECR and nearby extragalactic populations, short and long GRB and associated gravitational events, constraining stellar populations in galaxies and the Hubble constant, revealing the black hole population with gravitational waves
Probing extragalactic lines of sight : Extragalactic background light, InterGalactic Magnetic Field, search for LIV signatures in signals from AGN and GRB, contraints deduced for cosmology and fundamental physics, CTA sciences
