The paper discusses the fate of massive single stars, focusing on the factors that determine their explosion type and remnant. The authors explore how metallicity affects stellar evolution and the final outcome, mapping the regions where black holes and neutron stars form, and where different types of supernovae occur. They consider the role of stellar winds in mass loss, the impact of rotation on explosion mechanisms, and the implications for gamma-ray bursts and jet-driven supernovae. The study also examines the uncertainties in mass loss rates, explosion mechanisms, and the effects of rotation, and provides predictions for the distribution of compact remnants and observable outbursts in the universe.The paper discusses the fate of massive single stars, focusing on the factors that determine their explosion type and remnant.
