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…

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…

Detection of an Extremely Luminous Radio Counterpart to the Be/X-ray Binary A0538-66

Justine Crook-Mansour, Rob Fender, Alex Andersson +14

We present the discovery of radio emission from the Be/X-ray binary A0538-66 with the Australian Square Kilometre Array Pathfinder (ASKAP), and results from a subsequent weekly mon…

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…
