Measuring the Hubble constant and spatial curvature from supernova apparent magnitude, baryon acoustic oscillation, and Hubble parameter data

Chan-Gyung Park, Bharat Ratra

Cosmic microwave background (CMB) anisotropy (spatial inhomogeneity) data provide the tightest constraints on the Hubble constant, matter density, spatial curvature, and dark energ…

Median Statistics Analysis of Deuterium Abundance Measurements and Spatial Curvature Constraints

Jarred Penton, Jacob Peyton, Aasim Zahoor +1

Zavarygin et al. (2018) compiled a list of 15 deuterium abundance measurements, discarded two because the remaining 13 measurements are then consistent with gaussianity, and found…

Observational constraints on the tilted spatially-flat and the untilted nonflat CDM dynamical dark energy inflation models

Chan-Gyung Park, Bharat Ratra

We constrain spatially-flat tilted and nonflat untilted scalar field () dynamical dark energy inflation (CDM) models by using Planck 2015 cosmic microwave background (CMB) an…

A map-based method for eliminating systematic modes from galaxy clustering power spectra with application to BOSS

B. Bahr-Kalus, W. J. Percival, D. J. Bacon +5

We develop a practical methodology to remove modes from a galaxy survey power spectrum that are associated with systematic errors. We apply this to the BOSS CMASS sample, to see if…

Chan-Gyung Park, Bharat Ratra

We constrain tilted spatially-flat and untilted nonflat XCDM dynamical dark energy inflation parameterizations using Planck 2015 cosmic microwave background (CMB) anisotropy data a…

Using the tilted flat-CDM and the untilted non-flat CDM inflation models to measure cosmological parameters from a compilation of observational data

Chan-Gyung Park, Bharat Ratra

We use the physically-consistent tilted spatially-flat and untilted non-flat CDM inflation models to constrain cosmological parameter values with the Planck 2015 cosmic microwav…
