Constraints on power law cosmology from cosmic chronometer, standard ruler, and standard candle data (2102.08457v2)
Published 16 Feb 2021 in astro-ph.CO, gr-qc, hep-ph, and hep-th
Abstract: In this paper I investigate how well simple power law expansion fits observational data in comparison to the standard $\Lambda$CDM model. I analyze a data set consisting of cosmic chronometer, standard ruler, and standard candle measurements, finding that the $\Lambda$CDM model provides a better fit to most combinations of these data than the power law ansatz.
