The Impact of Different Neutrino Transport Methods on Multidimensional Core-collapse Supernova Simulations

Understand

Neutrinos play a crucial role in the core-collapse supernova (CCSN) explosion mechanism.

• The requirement of accurately calculating the transport of neutrinos makes simulations of the CCSN mechanism extremely challenging and computationally expensive.
• Historically, this stiff challenge has been met by making approximations to the full transport equation.
• In this work, we compare CCSN simulations in one- and two-dimensions with three approximate neutrino transport schemes, each implemented in the {\tt FLASH} simulation framework.
