JWST difference imaging from COSMOS-Web and PRIMER has yielded 68 high-redshift supernovae including a core-collapse event at z>3 and a Type Ia at z>2, demonstrating the feasibility of wide-area time-domain searches in the early universe.
Discovery of a gravitationally lensed Type II supernova at z=1.37 with magnification ≳100×, confirmed via multi-telescope spectra and imaging.
New H0 = 67.0 +9.3/-7.8 km/s/Mpc from joint lens-model fit to time delays of SN Requiem and SN Encore in MACS J0138.0-2155.
A convLSTM classifier identifies lensed SNe Ia in simulated LSST-like time series, reaching ~60% true-positive rate at O(10^{-4}) false-positive rate by the seventh epoch even after adding realistic PSF variations and foreground SN contaminants.
