ASTERIA: A Supernova TEst Routine for IceCube Analysis

ASTERIA is a fast supernova neutrino simulation designed for the IceCube Neutrino Observatory. The original version, called the Unified Supernova Simulation Routine (USSR), was written in C++ by Thomas Kowarik and Gösta Kroll at Universität Mainz in 2011. This project began as a Python port of the original program.

The code uses estimates of the supernova neutrino luminosity from large-scale simulations of core-collapse supernovae to calculate photons in the IceCube detector. The calculation includes parameterizations of the most important interactions contributing to signal in the ice from core-collapse neutrinos:

• Inverse beta decay.

• Electron scattering.

• Charged-current interactions on ¹⁶O.

• Neutral-current interactions on ¹⁶O.

• Scattering on ^17/18O.

Details are available in R. Abbasi et al., IceCube sensitivity for low-energy neutrinos from nearby supernovae, A&A 535:A109, 2011.

Access to supernova neutrino simulations is provided through the SNEWPY code, documented on readthedocs and github.
