The SkyLLH framework for IceCube point-source search — •Tomas Kontrimas and Martin Wolf for the IceCube collaboration — Technische Universität München

The hypothesis tests with unbinned log-likelihood (LLH) functions are a common technique used in multi-messenger astronomy, including IceCube's neutrino point-source searches. We present the general Python-based tool "SkyLLH", which provides a modular framework for implementing and executing log-likelihood functions to perform data analyses with recorded multi-messenger astronomy data from multiple experiments. Specific SkyLLH framework features for a new and improved IceCube point-source analysis are highlighted, including the support for kernel density estimation (KDE) based probability density functions. In addition, the future development goals of the SkyLLH framework as a common analysis tool for the multi-messenger community will be discussed.
