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…

EMU discovery of Thunder: a bow-shock PWN powered by PSR J1631-4722 escaping Nimbus SNR (G336.7+0.5)

S. Lazarević, C. Maitra, A. Ahmad +21

We report the discovery of a bow-shock pulsar wind nebula (PWN), dubbed Thunder, powered by the radio pulsar PSR J1631-4722 and projected within the Galactic supernova remnant (SNR…

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…

ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)

M. D. Filipović, Z. J. Smeaton, A. C. Bradley +33

We report diffuse extended radio-continuum emission spatially coinciding with the IR source WISEA J094409.17-751012.8, and a semi-variable star, V687 Carinae. We use 944 MHz radio…

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…
