A long-period radio transient active for three decades
N. Hurley-Walker, N. Rea, S. J. McSweeney +22
Recently several long-period radio transients have been discovered, with strongly polarised coherent radio pulses appearing on timescales between tens to thousands of seconds [1,2]…
A radio transient with unusually slow periodic emission
N. Hurley-Walker, X. Zhang, A. Bahramian +7
The high-frequency radio sky is bursting with synchrotron transients from massive stellar explosions and accretion events, but the low-frequency radio sky has so far been quiet bey…
Ultra-deep ATCA imaging of 47 Tucanae reveals a central compact radio source
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +9
We present the results of an ultra-deep radio continuum survey, containing hours of observations, of the Galactic globular cluster 47 Tucanae with the Australia Telescope…
Interactions between the jet and disk wind in a nearby radio intermediate quasar III Zw 2
Ailing Wang, Tao An, Shaoguang Guo +13
Disk winds and jets are ubiquitous in active galactic nuclei (AGN), and how these two components interact remains an open question. We study the radio properties of a radio-interme…
Rapid radio brightening of GRB 210702A
G. E. Anderson, T. D. Russell, H. M. Fausey +16
We observed the rapid radio brightening of GRB 210702A with the Australian Telescope Compact Array (ATCA) just 11hr post-burst, tracking early-time radio variability over a 5hr per…
Constraining the nature of the 18-min periodic radio transient GLEAM-X J162759.5-523504.3 via multi-wavelength observations and magneto-thermal simulations
N. Rea, F. Coti Zelati, C. Dehman +13
We observed the periodic radio transient GLEAM-X J162759.5-523504.3 (GLEAM-X J1627) using the Chandra X-ray Observatory for about 30-ks on January 22-23, 2022, simultaneously with…
Mysterious Odd Radio Circle near the Large Magellanic Cloud -- An Intergalactic Supernova Remnant?
Miroslav D. Filipović, J. L. Payne, R. Z. E. Alsaberi +48
We report the discovery of J0624-6948, a low-surface brightness radio ring, lying between the Galactic Plane and the Large Magellanic Cloud (LMC). It was first detected at 888 MHz…
Radio Emission from Interstellar Shocks: Young Type Ia Supernova Remnants and the Case of N 103B in the Large Magellanic Cloud
R. Z. E. Alsaberi, L. A. Barnes, M. D. Filipovic +19
Here we present a radio continuum study based on new and archival data from the Australia Telescope Compact Array towards N 103B, a young (<=1000 yrs) spectroscopically confirmed t…
Deep XMM-Newton observations of the northern disk of M31 II: Tracing the hot interstellar medium
Patrick J. Kavanagh, Manami Sasaki, Dieter Breitschwerdt +10
Aims: We use new deep XMM-Newton observations of the northern disk of M 31 to trace the hot interstellar medium (ISM) in unprecedented detail and to characterise the physical prope…
Deep XMM-Newton observations of the northern disc of M31. I. Source catalogue
M. Sasaki, F. Haberl, M. Henze +12
We carried out new observations of two fields in the northern ring of M31 with XMM-Newton with two exposures of 100 ks each and obtained a complete list of X-ray sources down to a…
A Morphological Study of the Supernova Remnant RX J0852.0-4622 (Vela Jr.)
Nigel I. Maxted, M. D. Filipovic, H. Sano +14
We conduct a multi-wavelength morphological study of the Galactic supernova remnant RXJ0852.0-4622 (also known as Vela Jr., Vela Z and G266.2-1.2). RX J0852.0-4622 is coincident wi…
