Testing the Mutual Consistency of the Pantheon and SDSS/eBOSS BAO Data Sets with Gaussian Processes
Ryan E. Keeley, Arman Shafieloo, Gong-Bo Zhao +2
We test the mutual consistency between the baryon acoustic oscillation measurements from the eBOSS SDSS final release, as well as the Pantheon supernova compilation in a model inde…
Model selection and parameter estimation using the iterative smoothing method
Hanwool Koo, Arman Shafieloo, Ryan E. Keeley +1
We compute the distribution of likelihoods from the non-parametric iterative smoothing method over a set of mock Pantheon-like type Ia supernova datasets. We use this likelihood di…
Inflation Wars: A New Hope
Ryan E. Keeley, Arman Shafieloo, Dhiraj Kumar Hazra +1
We explore a class of primordial power spectra that can fit the observed anisotropies in the cosmic microwave background well and that predicts a value for the Hubble parameter con…
Strong constraints on thermal relic dark matter from Fermi-LAT observations of the Galactic Center
Kevork N. Abazajian, Shunsaku Horiuchi, Manoj Kaplinghat +2
The extended excess toward the Galactic Center (GC) in gamma rays inferred from Fermi-LAT observations has been interpreted as being due to dark matter (DM) annihilation. Here, we…
Determining Model-independent and Consistency Tests
Kai Liao, Arman Shafieloo, Ryan E. Keeley +1
We determine the Hubble constant precisely ( uncertainty) in a manner independent of cosmological model through Gaussian process regression, using strong lensing and s…
Model-independent constraints on Type Ia supernova light-curve hyper-parameters and reconstructions of the expansion history of the Universe
Hanwool Koo, Arman Shafieloo, Ryan E. Keeley +1
We reconstruct the expansion history of the Universe using type Ia supernovae (SN Ia) in a manner independent of any cosmological model assumptions. To do so, we implement a non-pa…
