A Parsec-Scale Transient High-Frequency-Peaked Radio Source in the Very Large Array Sky Survey Brightening and Fading over a Decadal Timescale
Yuyang Chen, B. M. Gaensler, Maria R. Drout +10
A subset of active galactic nuclei (AGN) manifests as compact radio sources with peaked radio spectra, commonly referred to as peaked-spectrum (PS) sources. Generally, PS sources a…
Rapid Response Triggering for Radio Transients with the SKA Observatory
G. E. Anderson, S. I. Chastain, A. P. Curtin +10
Rapid-response triggering is when a telescope is able to automatically respond to an external or internal astronomical transient alert, causing it to rapidly repoint at that positi…
The Variability of Radio Stars
Laura N. Driessen, Alex Andersson, Joseph R. Callingham +6
Stellar radio emission is highly variable with stellar flares lasting from milliseconds to hours. For some stars, their flares or bursts can repeat once every couple of hours, whil…
Long-Period Transients as a new frontier in time-domain astronomy
Manisha Caleb, Dougal Dobie, Natasha Hurley-Walker +8
Long-period radio transients (LPTs) are relatively new astrophysical objects occupying the observational gap between canonical pulsars and slowly varying radio variables. They emit…
Supernovae with the Square Kilometre Array
Poonam Chandra, Yuhei Iwata, A. J. Nayana +2
This chapter presents the science potential of the Square Kilometre Array (SKA) for studying all classes of supernovae and their environments. It substantially updates and extends…
The X-ray emission of the long-period transient and accreting cataclysmic variable ASKAP J174508.9-505149
M. Imbrogno, M. Veresvarska, Y. L. Wang +8
Long-period transients (LPTs) challenge our knowledge of the mechanism producing radio periodic pulsations in compact objects. Some LPTs have been associated with systems hosting a…
The Rapid ASKAP Continuum Survey (RACS) VIII: total intensity and circular polarization images and catalogues at 887.5 MHz from RACS-low2
S. W. Duchesne, K. Rose, Tara Murphy +9
We present a new data release from the Rapid ASKAP Continuum Survey (RACS), a widefield snapshot radio survey conducted with the Australian SKA Pathfinder (ASKAP). This data releas…
Periodic Radio and X-ray Emission from an Accreting White Dwarf Binary
Kovi Rose, Joshua Pritchard, Tara Murphy +26
Long period radio transients (LPTs) are coherent bursts of polarised radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical o…
SN 2007it on the RISE -- a radio detection of an interacting supernova 18 years post-explosion
F. Acero, R. Z. E. Alsaberi, M. Arias +17
We report the first detection of radio emission from the Type II supernova SN 2007it, located at a distance of 12.2 Mpc in NGC 5530. The observations were obtained with the Austral…
Discovery of a 36-minute long-period transient ASKAP J142431.2-612611
Joshua Pritchard, Tara Murphy, Dougal Dobie +13
We report the discovery of a new long-period radio transient, ASKAP J142431.2-612611, with a 36 minute period, identified in the Australian SKA Pathfinder Evolutionary Map of the U…
The ASKAP Variables and Slow Transients (VAST) Extragalactic Survey - Data Release 1
Iris de Ruiter, Dougal Dobie, Tara Murphy +13
The Variables and Slow Transients (VAST) Survey on the Australian SKA Pathfinder (ASKAP) is designed to systematically explore the dynamic radio sky, detecting sources that vary on…
findAbar: how astronomers may perceive the bar in galaxies differently
Elizabeth J. Iles, Joss Bland-Hawthorn, Courtney Crawford +18
Bars are ubiquitous morphological features in the observed distribution of galaxies. There are similarly many methods for classifying these features and, without a strict theoretic…
RadioSED II: discovering the peaked spectrum radio sources in Stripe 82
E. F. Kerrison, E. M. Sadler, V. A. Moss +6
This paper is the second in a series presenting \textsc{RadioSED}, a Bayesian inference framework for constructing, modelling and classifying radio spectral energy distributions fr…
A new long period radio transient: Discovery of pulses repeating every 1.16 hours from ASKAP J175534.9-252749.1
Samuel J. McSweeney, Natasha Hurley-Walker, Csanád Horváth +7
We report the discovery of several new pulses from the source ASKAP J175534.9-252749.1 (J1755-2527), originally identified from a single 2-min long pulse, confirming it as a long p…

Akash Anumarlapudi, David L. Kaplan, Nanda Rea +13
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarized radio bursts with periods varying from a few minutes to a few hours. Fewe…
Discovery of Main-sequence Radio Pulse emitters from widefield sky surveys
Barnali Das, Matt E. Shultz, Joshua Pritchard +6
Magnetic AB stars are known to produce periodic radio pulses by the electron cyclotron maser emission (ECME) mechanism. Only 19 such stars, known as 'Main-sequence Radio Pulse emit…
