HEASA2025 - (other heasa conferences)
16-20 September 2025
University of Johannesburg, South Africa
University of Johannesburg, South Africa
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.
