Direct Detection of Type II-P Supernova Progenitors with the Euclid and CSST Surveys
Junjie Wu, Ning-Chen Sun, Zexi Niu +14
A central goal in supernova (SN) research is to identify and characterize their progenitors. However, this is very difficult due to the limited archival images with sufficient dept…
