Searching for Neutrinos From the Galactic Center Region with IceCube

The IceCube Neutrino Observatory has discovered astrophysical neutrinos. The Galactic Center (GC) has long been subject to intense astrophysics interest and is expected to emit high energy neutrinos. Many interesting phenomena such as high-mass X-ray binaries, supernova remnants, and etc., have been observed in this region. These phenomena are largely affected by a strong radio source at the GC, i.e. the super-massive black hole (Sgr. A*). A large amount of high energy neutrinos are expected to arise from these phenomena. However, the GC region is at a less sensitive part of the sky to the IceCube neutrino detector due to its location. Therefore, a dedicated dataset for the GC region needs to be created to improve data fidelity. This work focuses on event selection methods to build an analysis level dataset of the GC region. A boosted decision tree is used to select well reconstructed events and reduce data rate. Several calculations are developed to measure the stochasticity of the events. The stochasticity variables are used to reduce the high energy muon bundles, which can be mistakenly considered as single neutrino events. Comparing to a previous selection done on the southern sky, the sensitivity at the GC has been improved with this new dataset.
