A fast radio burst from a non-targeted low-frequency survey
Cristian Di Pietrantonio, Marcin Sokolowski, Clancy W. James +13
Fast radio bursts (FRBs) are bright, millisecond-duration transient radio signals of extragalactic origin with unknown source and emission mechanisms. While several thousand FRBs h…
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…
Detection of Cyclotron Absorption in the Radio Emission of GPM 1839-10
Yunpeng Men, Ewan Barr, Yuanhong Qu +8
GPM 1839-10 is an intriguing long-period radio transient (LPT), distinguished by its activity spanning at least three decades and its highly unusual emission characteristics. These…
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…
The ONs and OFFs of Pulsar Radio Emission: Characterizing the Nulling Phenomenon
Garvit Grover, N. D. Ramesh Bhat, Samuel J. McSweeney +4
Radio emission from pulsars is known to exhibit a diverse range of emission phenomena, among which nulling, where the emission becomes temporarily undetectable, is an intriguing on…
Investigating four new candidate redback pulsars discovered in the image plane
Flora Petrou, Natasha Hurley-Walker, Sam McSweeney +12
This paper reports the discovery and follow-up of four candidate redback spider pulsars: GPM J1723-33, GPM J1734-28, GPM J1752-30 and GPM J1815-14, discovered with the Murchison Wi…
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…
Einstein Probe discovery of the short period intermediate polar EP J115415.8-501810
Y. Xiao, M. Ge, N. Rea +21
The X-ray transient source EP240309a/EP\,J115415.8501810 was first detected by the Wide-Field X-ray Telescope (WXT) on board Einstein Probe (EP) during the commissioning phase.…
A binary model of long period radio transients and white dwarf pulsars
Csanád Horváth, Nanda Rea, Natasha Hurley-Walker +3
Long-period radio transients (LPTs) represent a recently uncovered class of Galactic radio sources exhibiting minute-to-hour periodicities and highly polarised pulses of second-to-…
100,000 Crab giant pulses at 215 MHz detected with an SKA-Low prototype station
M. Sokolowski, P. Kumar, S. Dhavali +4
We report detection and analysis of the largest low-frequency (200 - 231.25 MHz) sample of Crab giant pulses (GPs) reported in the literature. In total about 95000 GPs were detecte…
Discovery of an RRAT-like pulsar via its single pulses in an MWA imaging survey
Samuel J. McSweeney, Jared Moseley, Natasha Hurley-Walker +5
We report the discovery of PSR J00315726 in the GaLactic and Extragalactic All-sky MWA eXtended imaging survey at a Galactic latitude of . The pulsar exhibi…
A highly magnetized long-period radio transient exhibiting unusual emission features
Yunpeng Men, Sam McSweeney, Natasha Hurley-Walker +2
Long-period radio transients are a new class of astrophysical objects that exhibit periodic radio emission on timescales of tens of minutes. Their true nature remains unknown; poss…
The emission of interpulses by a 6.45-hour period coherent radio transient
Y. W. J. Lee, M. Caleb, Tara Murphy +29
Long-period radio transients are a novel class of astronomical objects characterised by prolonged periods ranging from 18 minutes to 54 minutes. They exhibit highly polarised, cohe…
Detection of X-ray Emission from a Bright Long-Period Radio Transient
Ziteng Wang, Nanda Rea, Tong Bao +46
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…
An emission state switching radio transient with a 54 minute period
M. Caleb, E. Lenc, D. L. Kaplan +19

Discovery and follow-up of a quasiperiodically nulling and sub-pulse drifting pulsar with the Murchison Widefield Array
G. Grover, N. D. R. Bhat, S. McSweeney +4
The phenomenon of pulsar nulling, where pulsars temporarily and stochastically cease their radio emission, is thought to be indicative of a `dying' pulsar, where radio emission cea…
