Supernovae and the Era of Synoptic Surveys
summary
Survey history and hard numbers: a pipeline built around the Palomar Transient Factory finds ~1–3 supernovae per night, produces 1.8 million subtractions and a billion candidates over years, and yields ~3,000 spectroscopically typed supernovae. Real-time system engineering cuts median discovery-to-action time to ~40 minutes (worst ~1 hour), with nightly bandwidth, IO and kernel updates regularly causing outliers. Upgrades scale to the Zwicky Transient Facility (47 deg², 30 s exposures) and force prioritization and randomized follow-up to avoid missing rare fast transients.
