HEASA 2019 was the seventh conference in the annual series "High Energy Astrophysics in Southern Africa".
Its goal was to bring together scientists from the southern African region, the African continent, and around the world, with an interest in high-energy astrophysical phenomena. Topics discussed include theoretical and multi-wavelength and multi-messenger observational aspects of active galactic nuclei, galaxy systems, gamma-ray bursts, X-ray/gamma-ray binaries, supernovae and supernova remnants, neutron stars, pulsars and pulsar wind nebulae, cataclysmic variables, and modern aspects of astro-particle physics.

HEASA2019 was hosted by the University of Namibia and took place at the Ministry of Fisheries and Marine Resources Auditorium in Swakopmund, August 28 - 30, 2019. It was sponsored by the Department of Science and Technology and the National Research Foundation of South Africa through the South African Gamma-Ray Astronomy Programme (SA-GAMMA) and the University of Namibia‘s Office of the Pro-Vice Chancellor Research, Innovation and Development.
