Superphot+: Realtime Fitting and Classification of Supernova Light Curves

Understand

Photometric classifications of supernova (SN) light curves have become necessary to utilize the full potential of large samples of observations obtained from wide-field photometric surveys, such as the Zwicky Transient Facility (ZTF) and the Vera C.

• Rubin Observatory.
• Here, we present a photometric classifier for SN light curves that does not rely on redshift information and still maintains comparable accuracy to redshift-dependent classifiers.
• Our new package, Superphot+, uses a parametric model to extract meaningful features from multiband SN light curves.
