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…

Radio detection of supernova remnant G310.7-5.4 with -ray counterpart: Abeona SNR

Christopher Burger-Scheidlin, Brianna D. Ball, Sanja Lazarević +10

G310.7-5.4 is a supernova remnant (SNR) candidate identified as a faint shell in the second epoch Molonglo Galactic Plane Survey (MGPS-2), but this has not been followed up with mu…

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…

EMU/GAMA: Refining Dust Extinction Corrections for Hα Luminosity Functions Using Radio-Based Calibration

J. Willingham, A. Hopkins, T. Zafar +17

We present a novel approach to correcting H luminosity functions for dust extinction by calibrating against radio-based star formation rates (SFRs), using data from the Evoluti…

EMU Radio Observations of Barred Spiral Galaxy NGC 5938 (Araish)

H. Zakir, M. D. Filipović, L. Barnes +14

We present multi-wavelength observations of the nearby spiral galaxy NGC 5938 (Araish) to investigate the origin of its radio emission, specifically the contribution from active ga…

Stingrays in the radio sky: Two unusual diffuse radio relic sources in the direction of the Magellanic Stream

Zachary J Smeaton, Miroslav D Filipovic, Barbel S Koribalski +17

We present the discovery of two extended, low surface brightness radio continuum sources, each consisting of a near-circular body and an extended tail of emission, nicknamed Stingr…
