FRB20250613A is a repeating FRB discovered by the Australian SKA Pathfinder and localised to a low-metallicity dwarf galaxy at a redshift of . FRB 20250613A…
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…
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…

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…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
Discovery of Two Highly Scattered Pulsars from Image-Based Circular Polarization Searches with the Australian SKA Pathfinder
Rahul Sengar, David L. Kaplan, Emil Lenc +6
We report the discovery and timing of two pulsars from a sample of four circularly polarized sources identified in radio continuum images taken as part of the Australian SKA Pathfi…
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…
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 Search for Low-frequency Radio Pulses from Long Gamma-ray Bursts with the Murchison Widefield Array
Fan Xu, G. E. Anderson, Jun Tian +10
It has been proposed that coherent radio emission could be emitted during or shortly following a gamma-ray burst (GRB). Here we present a low-frequency ( MHz) search for r…
The radio afterglow of the ultra-long GRB 220627A
James K. Leung, Om Sharan Salafia, Cristiana Spingola +13
We present the discovery of the radio afterglow of the most distant ultra-long gamma-ray burst (GRB) detected to date, GRB~220627A at redshift . Its prompt gamma-ray light…
Detection of X-ray Emission from a Bright Long-Period Radio Transient

Recently, a class of long-period radio transients (LPTs) has been discovered, exhibiting emission on timescales thousands of times longer than radio pulsars. Several models had bee…
Radio afterglows from tidal disruption events: An unbiased sample from ASKAP RACS
Akash Anumarlapudi, Dougal Dobie, David L. Kaplan +23
Late-time ( year) radio follow-up of optically-discovered tidal disruption events (TDEs) is increasingly resulting in detections at radio wavelengths, and there is growing ev…
