A model-independent method fits blended supernova light curves as superpositions of two time-delayed components and finds only one candidate above a 12-day delay threshold in 445 ZTF Type Ia supernovae, for a 0.22% false positive rate.

Finding Strongly Lensed Supernovae from Blended Light Curves
A model-independent method fits blended supernova light curves as superpositions of two time-delayed components and finds only one candidate above a 12-day delay threshold in 445 ZTF Type Ia supernovae, for a 0.22% false positive rate.
