Tidal Disruption Events with the SKA
T. An, A. J. Goodwin, J. C. A. Miller-Jones +3
The paper outlines how the Square Kilometre Array’s sensitivity, wide frequency coverage, and VLBI capabilities will enable large‑scale radio studies of tidal disruption events, im…
SKAVLBI view of AGN jets in the early Universe
C. Spingola, M. Mezcua, Y. Liu +33
Active Galactic Nuclei (AGN) are among the brightest sources in the Universe, and those that are also jetted are uniquely valuable at the earliest epochs, because their relativisti…
Gamma-ray Bursts in the Radio Sky: the Role of the SKA-VLBI
Stefano Giarratana, Om Sharan Salafia, Xue-Feng Wu +6
Radio observations of -ray bursts (GRBs) employing the very long baseline interferometry (VLBI) technique provide us with fundamental information on the dynamics and the geomet…
EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction
Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100
We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…
The radio afterglow of the ultra-long GRB 220627A
James K. Leung, Om Sharan Salafia, Cristiana Spingola +13
We present the discovery of the radio afterglow of the most distant ultra-long gamma-ray burst (GRB) detected to date, GRB~220627A at redshift . Its prompt gamma-ray light…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
