IceTray UHE Neutrino Reconstructions Analysis.

The IceCube Neutrino Observatory is a cubic kilometer hexagonal lattice deployed at the South Pole comprised of photomultiplier tubes to detect Cherenkov light from neutrino-nucleon interactions in the ice. Methods of ultra-high energy (UHE) event reconstruction used by IceCube remain key components in pointing to possible neutrino sources in extremely distant parts of the universe. In this study,~high performance distributed cluster computing using SLURM and~Monte Carlo simulated neutrino and muon events were used in the analysis of Ophelia and LineFit reconstruction techniques. Cuts were applied to select for bright, charge-current interaction events. Error analysis and energy dependence comparisons showed that Ophelia and LineFit have comparable accuracies for UHE neutrino reconstructions, and it was demonstrated that~new reconstruction algorithms can be used that are better supported and more robust.
