Beyond Fisher Forecasting for Cosmology
Joseph Ryan, Brandon Stevenson, Cynthia Trendafilova +1
The planning and design of future experiments rely heavily on forecasting to assess the potential scientific value provided by a hypothetical set of measurements. The Fisher inform…
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 CDM 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…
Cosmological constraints from higher-redshift gamma-ray burst, HII starburst galaxy, and quasar (and other) data
Shulei Cao, Joseph Ryan, Narayan Khadka +1
We use higher-redshift gamma-ray burst (GRB), HII starburst galaxy (HIIG), and quasar angular size (QSO-AS) measurements to constrain six spatially flat and non-flat cosmological m…
