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…

Tracing cosmic star formation history through radio continuum spectral energy distribution and non-thermal emission

Fangxia An, Fatemeh S. Tabatabaei, Nick Seymour +11

The paper reviews how radio continuum emission, especially mid‑radio (1–10 GHz) luminosity and spectral shape, can be used as a dust‑unbiased tracer of star formation rates and the…
