SKAO and Gamma-Ray Synergies
Gianluca Castignani, Gavin Rowell, Arnau Aguasca-Cabot +26
A wide variety of Galactic and extragalactic sources are known to emitradiation across the entire electromagnetic spectrum, including both transient and steady-state phenomena. A f…
Discovery of Molecular and Atomic Gas associated with HESS J1646-458 (Westerlund 1): Spatial TeV Gamma-Ray and Interstellar Proton Correspondence
H. Sano, Y. Fukui, S. Fujimori +21
We report CO and HI studies of molecular and atomic gas toward the TeV gamma-ray source HESS J1646458, widely considered to be associated with the young massive cluster Westerlu…
Scrutinizing the 2020 multiwavelength outburst of PKS 0903-57 through observations with H.E.S.S
A. Acharyya, F. Aharonian, F. Ait Benkhali +138
The blazar PKS 0903-57 has recently been classified as a flat spectrum radio quasar at a redshift of . In March and April 2020, Fermi-LAT and AGILE reported tremendous ac…
Case study of a national-level academic conference organised in hybrid mode at low cost
Violet M. Harvey, Simon Lee, Bruce Dawson +2
In July 2025, the University of Adelaide hosted the Astronomical Society of Australia's Annual Scientific Meeting on its North Terrace campus. We ran the conference in a hybrid mod…
Gas Kinematics and Cosmic-Ray Acceleration in the Gamma-ray SNRs W41 and G22.7-0.2
Takeru Murase, Hidetoshi Sano, Kohei Matsubara +13
We present a study of the interstellar medium associated with the two middle-aged supernova remnants (SNRs) W41 and G22.7-0.2, both detected in TeV gamma-rays. Using high-angular-r…
Prompt Searches for Very-High-Energy γ-Ray Counterparts to IceCube Astrophysical Neutrino Alerts
J. Abhir, A. Biland, K. Brand +817
The search for sources of high-energy astrophysical neutrinos can be significantly advanced through a multi-messenger approach, which seeks to detect the gamma rays that accompany…
