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…

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…

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…

Late-Time Supernovae Radio Re-brightening in the VAST Pilot Survey

Kovi Rose, Assaf Horesh, Tara Murphy +12

We present our analysis of supernovae serendipitously found to be radio-bright several years after their optical discovery. We used recent observations from the Australian SKA Path…

Rocking the BOAT: the ups and downs of the long-term radio light curve for GRB 221009A

L. Rhodes, A. J. van der Horst, J. S. Bright +24

We present radio observations of the long-duration gamma-ray burst (GRB) 221009A which has become known to the community as the Brightest Of All Time or the BOAT. Our observations…

An emission state switching radio transient with a 54 minute period

M. Caleb, E. Lenc, D. L. Kaplan +19

Long-period radio transients are an emerging class of extreme astrophysical events of which only three are known. These objects emit highly polarised, coherent pulses of typically…
