Amy Lien, Nachiketa Chakraborty, Brian D. Fields, Athol Kemball

TL;DR
This paper discusses how upcoming radio telescopes like SKA will revolutionize the detection and study of radio supernovae, enabling comprehensive statistical analyses and insights into supernova physics and stellar evolution.
Contribution
It predicts the capabilities of next-generation radio telescopes to detect and analyze radio supernovae across a wide redshift range, including the potential detection of radio Type Ia supernovae.
Findings
SKA will detect core-collapse RSNe up to z ~ 5
Estimated detection rate of ~620 events per year per square degree with SKA
EVLA and other precursors will detect hundreds of RSNe annually
Abstract
Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae have been detected at radio wavelengths, none of which are Type Ia. Even the most radio-loud events are ~ 10^4 fainter in the radio than in the optical; to date, such intrinsically dim objects have only been visible in the very local universe. The detection and study of radio supernovae (RSNe) will be fundamentally altered and dramatically improved as the next generation of radio telescopes comes online, including EVLA, ASKAP, and MeerKAT, and culminating in the Square Kilometer Array (SKA); the latter should be > 50 times more sensitive than present facilities. SKA can repeatedly scan large (> 1 deg^2) areas of the sky, and thus will discover RSNe and other transient sources in a new,…
