Constraints on power law cosmology from cosmic chronometer, standard ruler, and standard candle data

Joseph Ryan

In this paper I investigate how well simple power law expansion fits observational data in comparison to the standard ΛCDM model. I analyze a data set consisting of cosmic chrono…

Using Pantheon and DES supernova, baryon acoustic oscillation, and Hubble parameter data to constrain the Hubble constant, dark energy dynamics, and spatial curvature

Shulei Cao, Joseph Ryan, Bharat Ratra

We use Pantheon Type Ia supernova (SN Ia) apparent magnitude, DES-3yr binned SN Ia apparent magnitude, Hubble parameter, and baryon acoustic oscillation measurements to constrain s…
