Descripción
The IceCube Neutrino Observatory investigates high-energy astrophysical phenomena by studying the corresponding high-energy neutrino signal. Its successful discovery of a diffuse flux of astrophysical neutrinos with energies up to the PeV scale in 2013 has triggered a vast effort to identify this signal's sources, which recently resulted in an improved analysis method. Here, we present a new IceCube point-source search that improves the accuracy of the statistical analysis, especially at energies of a few TeV and below. The new approach includes multidimensional kernel density estimation based probability density functions, angular error estimates using a boosted decision tree, and a new deep neural network energy estimator.
