After the successful eleventh conference in the annual series, High Energy Astrophysics in Southern Africa 2023 (HEASA 2023) held at the WITS Rural Facility, Kruger National Park, South Africa, the twelve conference, HEASA 2025, will continue its mission of uniting scientists from the Southern African region, the African continent, and around the world who share an interest in high-energy astrophysical phenomena.
The topics to be discussed at HEASA 2025 include theoretical aspects, multi-wavelength observations, and multi-messenger studies of astrophysical sources. These sources encompass a wide range, such as active galactic nuclei (AGNs), galaxy systems, gamma-ray bursts (GRBs), X-ray/gamma-ray binaries, supernovae and supernova remnants, neutron stars, pulsars, pulsar wind nebulae, and cataclysmic variables (CVs). Additionally, the conference will explore modern aspects of Astro-particle physics.
