Abstract:
The richness of high-energy transient phenomena in the universe—ranging from fast radio bursts to gamma-ray flares and gravitational-wave events—is often associated with compact objects such as neutron stars and black holes. We have now entered the multi-messenger era, which brings both the opportunity and the challenge of studying these phenomena across electromagnetic, gravitational, and neutrino channels simultaneously. In this context, numerical simulations are becoming an increasingly essential tool, capable of bridging the gap between theoretical models and multi-faceted observations. In this talk, I will present how multiple numerical techniques can be used to study compact object systems. I will focus on three examples: single magnetar magnetosphere and fast radio bursts, binary neutron star mergers and supermassive black hole binaries.
