TL;DR
This paper discusses the potential of radio sky surveys to discover more supernovae, understand stellar evolution, and aid in identifying electromagnetic counterparts to gravitational wave sources, emphasizing the importance for future radio facilities.
Contribution
It advocates for medium-area radio sky surveys at C-band or S-band to uncover hidden supernovae and support multi-messenger astronomy with upcoming radio telescopes.
Findings
Radio supernovae are undercounted due to optical obscuration.
A radio survey can reveal a larger supernova population.
Radio observations are crucial for multi-messenger astronomy.
Abstract
In the last three decades, about 50 radio supernovae have been detected as a result of targeted searches of optically discovered supernovae in the local universe. Despite this relatively small number some diversity among them has already been identified which is an indication of the underlying richness of radio supernovae waiting to be discovered. For example, comparison of star formation and supernova discovery rate imply that as many as half of the supernovae remain undetected in the traditional optical searches, either because of intrinsic dimness or due to dust obscuration. This has far reaching consequences to the models of stellar and galaxy evolution. A radio sky survey would be ideal to uncover larger supernova population. Transient radio sky would benefit significantly from such a survey. With the advent of advanced gravitational wave detectors a new window is set to open on…
