Description
Multi-dimensional instabilities coupled with magnetic fields, such as the magnetorotational instability (MRI), are considered important contributors to the explosion mechanism of core-collapse supernovae in extreme scenarios. In this work, we present three-dimensional simulations of a 40-solar-mass progenitor using the GPU-accelerated magnetohydrodynamics code GAMER. We investigate the effects of magnetic field strength, initial rotation, and spatial resolution on the explosion dynamics and resulting multi-messenger signals. Our preliminary results indicate that MRI can be triggered in the convective region within the proto-neutron star when the spatial resolution reaches below 250 meters. The development of MRI leaves distinct multi-messenger signatures, which may be detectable in future gravitational wave observations.
