Enhanced Astrometry of the Rapid ASKAP Continuum Survey: Mid and High Frequency Epochs
Akhil Jaini, Adam T. Deller, Yuanming Wang +4
Accurate radio astrometry is essential for reliable cross-identification of sources across wavelengths, precision localisation of transient events, and the construction of stable a…
VASTER: The ASKAP real-time fast-imaging pipeline -- overview and discovery of two long period transients
Yuanming Wang, Dougal Dobie, Tara Murphy +22
Recent developments in widefield radio telescopes have enabled searches of a new region of parameter space in the time domain: timescales of seconds to minutes, that have been over…

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…
AT 2024wpp: the most luminous fast-evolving optical transient linked to the merger explosion of a black-hole binary
Jialian Liu, Bao Wang, Xiaofeng Wang +48
Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
A fast radio burst cyclone in technicolour: evidence of plasma lensing
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are bright, energetic, radio pulses of extragalactic origin. A dichotomy has emerged in the population: some produce repeat bursts, while the majority do n…
Discovery of the redback millisecond pulsar PSR J1728-4608 with ASKAP
F. Petrou, Y. Wang, N. Hurley-Walker +10
We present the discovery of PSR J1728-4608, a new redback spider pulsar identified in images from the Australian SKA Pathfinder telescope. PSR J1728-4608 is a millisecond pulsar wi…
Searching for Long-Period Radio Transients in ASKAP EMU Data with 10-Second Imaging
Yu Wing Joshua Lee, Yuanming Wang, Manisha Caleb +10
Long-period radio transients (LPTs) are a recently identified phenomenon that challenge our current understanding of compact objects and coherent radio emission mechanisms. These o…
Sensitive Constraints on Coherent Radio Emission from Five Isolated White Dwarfs
Lei Zhang, Alexander Wolszczan, Joshua Pritchard +8
Coherent, periodic radio emission from pulsars has been widely interpreted as evidence of neutron stars as strongly magnetized compact objects. In recent years, radio pulses have a…
The Distribution of Atomic Hydrogen in the Host Galaxies of FRBs
Hugh Roxburgh, Marcin Glowacki, Clancy W. James +14
We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quad…
Unveiling the Cosmic Dance of Repeated Nuclear Transient ASASSN-14ko: Insights from Multiwavelength Observations
Shifeng Huang, Tinggui Wang, Ning Jiang +15
ASASSN-14ko is a periodically repeating nuclear transient. We conducted high-cadence, multiwavelength observations of this source, revealing several recurrent early bumps and rebri…
The Low-mass Dwarf Host Galaxy of Nonrepeating FRB 20230708A

We present deep optical and near-infrared observations of the host galaxies of 34 fast radio bursts (FRBs) detected by the Commensal Real-time ASKAP Fast Transient (CRAFT) survey o…
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…
VAST-MeMeS: Characterising non-thermal radio emission from magnetic massive stars using the Australian SKA Pathfinder
Barnali Das, Laura N. Driessen, Matt E. Shultz +7
Magnetic massive stars are stars of spectral types O, B and A that harbour kG strength (mostly dipolar) surface magnetic fields. Their non-thermal radio emission has been de…
The discovery of a 41s radio pulsar PSR J0311+1402 with ASKAP
Yuanming Wang, Pavan Uttarkar, Ryan Shannon +16
The emerging population of long-period radio transients (LPTs) show both similarities and differences with normal pulsars. A key difference is that their radio emission is too brig…
A depolarisation census of ASKAP fast radio bursts
Pavan A. Uttarkar, Ryan M. Shannon, Kelly Gourdji +9
Fast radio bursts (FRBs) are luminous, dispersed pulses of extra-galactic origin. The physics of the emission mechanism, the progenitor environment, and their origin are unclear. S…
