SNEWPY: A Data Pipeline from Supernova Simulations to Neutrino Signals
Résumé
Current neutrino detectors will observe hundreds to thousands of neutrinos from a Galactic
supernova, and future detectors will increase this yield by an order of magnitude or more.
With such neutrino data sets, the next Galactic supernova will significantly increase our un-
derstanding of the explosions of massive stars, nuclear physics under extreme conditions, and
the fundamental properties of neutrinos. However, there is a gulf between supernova simu-
lations and the corresponding signals in detectors, making comparisons between theory and
observation, as well as between different detectors, very difficult. SNEWPY offers a unified
interface for hundreds of supernova simulations, a large library of flux transformations on the
way towards the detector, and an interface to SNOwGLoBES (Scholberg & SNOwGLoBES
Contributors, 2021), allowing users to easily calculate and compare expected event rates from
many supernova models in many different neutrino detectors.
