Core-collapse and Type Ia supernovae with the SKA

Core-collapse SNe (CCSNe): Systematic searches of radio emission from CCSNe are still lack-ing, and only targeted searches of radio emission from just some of the optically discovered CCSNe in the local universe have been carried out. Optical searches miss a significant fraction of CCSNe due to dust obscuration; therefore, CCSN radio searches are much more promising for yielding the complete, unobscured star-formation rates in the local universe. The forthcoming SKA yields the possibility to piggyback for free in this area of research by carrying out commen-sal, wide-field, blind transient survey observations. SKA1-sur should be able to discover several hundreds of CCSNe in just one year, compared to about a dozen CCSNe that the VLASS would be able to detect in one year, at most. SKA, with an expected sensitivity ten times that of SKA1, is expected to detect CCSNe in the local Universe by the thousands. Therefore, commensal SKA observations could easily result in an essentially complete census of all CCSNe in the local uni-verse, thus yielding an accurate determination of the volumetric CCSN rate.
