HEASA 2022 was the ninth 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 included theoretical, multi-wavelength, and multi-messenger observational
aspects of astrophysical sources (e.g. active galactic nuclei (AGNs), galaxy systems, gamma-ray
bursts (GRBs), X-ray/gamma-ray binaries, supernovae and supernova remnants, neutron stars,
pulsars and pulsar wind nebulae, cataclysmic variables (CVs)) as well as modern aspects of
astro-particle physics. HEASA 2022 was held during the period of 28 September – 01 October
2022, as a hybrid conference with 42 in person contributions, 9 remote talks and 9 posters. It
was sponsored by the Department of Science and Innovation and the National Research
Foundation of South Africa through the South African Gamma-Ray Astronomy Programme (SA-
GAMMA).
