EMU discovery of Thunder: a bow-shock PWN powered by PSR J1631-4722 escaping Nimbus SNR (G336.7+0.5)
S. LazareviÄ, 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…
A newly born spider system at the core of a radio shell: Evidence for a low-energy supernova
S. LazareviÄ, R. Brose, L. M. Oskinova +24
In a search for low surface brightness radio nebulae using the ASKAP-EMU survey, we discovered a faint radio shell, G289.6+5.8, and its central point radio source at the position o…
ASKAP EMU detection of an Odd Radio Circle (ORC) candidate: J094412-751016 (Anglerfish)
M. D. FilipoviÄ, 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…
Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant
Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35
We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…
PSR J1631-4722: The Discovery of a Young and Energetic Pulsar in the Supernova Remnant G336.7+0.5
A. Ahmad, S. Dai, S. LazareviÄ +6
Detecting a pulsar associated with a supernova remnant (SNR) and/or pulsar wind nebula (PWN) is crucial for unraveling its formation history and pulsar wind dynamics, yet the assoc…
