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…
A long period transient search method for the Murchison Widefield Array
Csanád Horváth, Natasha Hurley-Walker, Samuel J. McSweeney +2
We present an automated search method for radio transients on the minute timescale focused on the emerging long period transients (LPTs) in image-plane radio data. The method is tu…
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…
