The 7th Heidelberg International Symposium on High-Energy Gamma-Ray Astronomy (γ-2022), will take place on July 4th to 8th 2022, in Barcelona, Spain.

The Gamma-Ray Symposium has been held since 1994 in Heidelberg, Germany (see the webpage of previous editions in 2000, 2004, 2008, 2012 and 2016). The 2020 edition had to be postponed due to the pandemic situation related to the COVID-19. We are now glad to announce that the Symposium will take place in 2022 and, for the first time, it will be held in Barcelona, hosted by the Institut de Ciències del Cosmos (ICCUB) of the University of Barcelona. It will closely follow the guidelines and structure of the previous Symposia, covering all major observational and theoretical aspects of the field with an emphasis on the high (GeV) and very high (TeV) energy intervals of the electromagnetic spectrum.

Scientific topics will range from the origin of galactic and extragalactic cosmic rays to the physics and astrophysics of compact objects and their relativistic outflows (Pulsars, Microquasars, Blazars, GRBs), PWNe, SNRs, Star Forming Regions, Giant molecular clouds and Interstellar Medium, as well as extragalactic non-thermal objects like Starburst Galaxies, Radio Galaxies and Galaxy Clusters. Cosmological issues related to Dark Matter, Intergalactic radiation and magnetic fields, and topics relevant to fundamental physics will also be addressed.

On behalf of LOC and SOC,
F. Aharonian, F. Rieger and J. M. Paredes
