(2019) Model independent expansion history from supernovae: Cosmology versus systematics. The 2nd international conference of the Energetic Cosmos Laboratory (ECL) at Nazarbayev University.

ECL Publication, 2019We examine the Pantheon supernovae distance data compilation in a model independent analysis to test the validity of cosmic history reconstructions beyond the concordance ΛCDM cosmology. Strong deviations are allowed by the data at z≳1 in the reconstructed Hubble parameter, Om diagnostic, and dark energy equation of state. We explore three interpretations: 1) possibility of the true cosmology being far from ΛCDM, 2) supernovae property evolution, and 3) survey selection effects.enAttribution-NonCommercial-ShareAlike 3.0 United StatesThe 2nd international conference of the Energetic Cosmos Laboratory (ECL)Energetic Cosmos Laboratory (ECL)ECL19Article
