A Detection of the Baryon Acoustic Oscillation Features in the SDSS BOSS DR12 Galaxy Bispectrum

David W. Pearson, Lado Samushia

We present the first high significance detection () of the Baryon Acoustic Oscillations (BAO) feature in the galaxy bispectrum of the twelfth data release (DR12) of the Baryo…

Planck 2015 constraints on the non-flat CDM inflation model

Junpei Ooba, Bharat Ratra, Naoshi Sugiyama

We perform Markov chain Monte Carlo analyses to put constraints on the non-flat CDM inflation model using Planck 2015 cosmic microwave background (CMB) anisotropy data and baryo…

First study of reionization in the Planck 2015 normalized closed CDM inflation model

Sourav Mitra, Tirthankar Roy Choudhury, Bharat Ratra

We study reionization in two non-flat CDM inflation models that best fit the Planck 2015 cosmic microwave background anisotropy observations, ignoring or in conjunction with bar…

The observational constraints on the flat CDM models

Olga Avsajanishvili, Yiwen Huang, Lado Samushia +1

Most dark energy models have the CDM as their limit, and if future observations constrain our universe to be close to CDM Bayesian arguments about the evidence and the fine-t…

Hubble Parameter and Baryon Acoustic Oscillation Measurement Constraints on the Hubble Constant, the Deviation from the Spatially-Flat cdm Model, The Deceleration-Acceleration Transition Redshift, and Spatial Curvature

Hai Yu, Bharat Ratra, Fa-Yin Wang

We compile a complete collection of reliable Hubble parameter data to redshift and use them with the Gaussian Process method to determine continuous fun…

Planck 2015 constraints on the non-flat XCDM inflation model

Junpei Ooba, Bharat Ratra, Naoshi Sugiyama

We study Planck 2015 cosmic microwave background (CMB) anisotropy data using the energy density inhomogeneity power spectrum generated by quantum fluctuations during an early epoch…

Inflation in a closed universe

Bharat Ratra

To derive a power spectrum for energy density inhomogeneities in a closed universe, we study a spatially-closed inflation-modified hot big bang model whose evolutionary history is…
