1. Cosmological Constraints for a Varying Dark Energy Model
Kandidat-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : This paper uses the Pantheon+ data set that consists of 1701 light curves of 1550 unique type IaSupernova to find constraints on various cosmological models and compare them with a varying darkenergy model proposed by Chevallier, Polarski and Linder in the early 2000s and analyze it deeper.The results show a tipping point from a decelerating universe to an accelerating one at a redshift ofz = 0.
