1100 Days in the Life of the Supernova 2018ibb - the Best #PairInstability #Supernova Candidate, to date: https://arxiv.org/abs/2305.05796 -> "The #PISN mechanism naturally provides both the energy source (56Ni) and the long diffusion time. [...] Powering by a central engine, such as a magnetar or a black hole, can be excluded with high confidence. This makes SN2018ibb by far the best candidate for being a PISN, to date."
