Nonparametric Dark Energy Reconstruction from Supernova Data
Tracy Holsclaw, Ujjaini Alam, Bruno Sanso +4
Understanding the origin of the accelerated expansion of the Universe poses one of the greatest challenges in physics today. Lacking a compelling fundamental theory to test, observ…
Analyzing and Visualizing Cosmological Simulations with ParaView
Jonathan Woodring, Katrin Heitmann, James Ahrens +4
The advent of large cosmological sky surveys - ushering in the era of precision cosmology - has been accompanied by ever larger cosmological simulations. The analysis of these simu…
Nonparametric Reconstruction of the Dark Energy Equation of State
Tracy Holsclaw, Ujjaini Alam, Bruno Sanso +4
A basic aim of ongoing and upcoming cosmological surveys is to unravel the mystery of dark energy. In the absence of a compelling theory to test, a natural approach is to better ch…
