Hints for possible low redshift oscillation around the best fit CDM model in the expansion history of the Universe
L. Kazantzidis, H. Koo, S. Nesseris +2
We search for possible deviations from the expectations of the concordance CDM model in the expansion history of the Universe by analysing the Pantheon Type Ia Supernovae (SnIa)…
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…
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…
