PoS - High Energy Phenomena in Relativistic Outflows IX

The High Energy Phenomena in Relativistic Outflows (HEPRO) conferences are a series of biennial events devoted to discussing the latest developments in theoretical, phenomenological, and observational high-energy and multi-messenger astrophysics, as well as relativistic winds and jets on all scales.

The ninth edition of the conference, HEPRO IX, took place in Rio de Janeiro, Brazil, at the historic Casa de Rui Barbosa site, from August 4 to 8, 2025. Specific topics addressed included the physics and dynamics of jets, as well as their multi-wavelength signatures; the production of cosmic rays, gamma rays, and neutrinos in relativistic outflows; the environments of compact objects; and the physics of relativistic sources, including pulsar wind nebulae, binary systems, gamma-ray bursts, and blazars, as well as particle acceleration.
