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…

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…
