he High Energy Phenomena in Relativistic Outflows (HEPRO) conference series are devoted to the discussion of the latest and more relevant observational, phenomenological, and theoretical developments in the field of high-energy astrophysics related to systems displaying relativistic winds and jets. Some specific topics traditionally included in the HEPRO conferences include gamma-ray production in relativistic outflows, multi-wavelength jet/outflow emission, formation and propagation of relativistic jets, and particle acceleration in different relativistic contexts.

Previous editions of HEPRO were held in Dublin (2007), in Buenos Aires (2009), in Barcelona (2011), in Heidelberg (2013), in La Plata (2015), and in Moscow (2017). On similar topics and with emphasis on physics of high-energy processes in all kinds of relativistic outflows, the next edition will take place in Barcelona on July 9th to 12th 2019.

The meeting will be hosted by the Institut de Ciències del Cosmos of the Universitat de Barcelona (ICCUB). The workshop will take place at the Faculty of Physics. The Lecture Room will be the Aula Magna Enric Casassas, which can accommodate up to 190 attendants. There will be invited and contributed talks, posters, and plenty of time for discussions.
