Surprisingly bright radio signals from old supernovae and TDEs: the beauty of an unbiassed view of the radio sky

The VLA Sky Survey (VLASS) has delivered the first deep, unbiased view of the northern radio sky, offering an unprecedented opportunity to perform a systematic and unbiased survey of the late-time radio emission from the tens of thousands of previously reported optical stellar explosions and tens of tidal disruption events. Interestingly, we found evidence for bright radio emission from several stellar explosions and tidal disruption events. In this talk I will review our current knowledge of the late-time radio emission from transients, and I will discuss the prospects for future observations to reveal the underlying physics of these bright displays.
