Early radio observations of supernovae - lessons from current time-domain surveys
The field of time domain is going through a revolution. Not only that the current large optical transient surveys allow the discovery of a plethora of supernovae, but an increasing number of supernovae are discovered at a young age, a few hours to a day after explosion. Combined with the new capabilities of radio observatories such as the Jansky Very Large Array, this enables a comprehensive pan-wavelength study of supernovae at an early stage. I will review our results from early radio observations of supernovae in the last year. In short, through our campaign, we were able to rule out a subset of type Ia supernova progenitors, learn about the microphysical parameters of type IIb supernova shockwaves and discover a fast evolving radio supernova. These latest results bode well for future studies of young supernovae discovered by LSST.
