MAGIC as a Neutrino Alert Follow-up Instrument — •Alicia Fattorini for the MAGIC collaboration — TU Dortmund

Despite the detection of a diffuse cosmic neutrino flux by the IceCube neutrino observatory in 2013, no neutrino point source has been detected yet. A promising approach for the first detection are the ongoing multi-messenger campaigns.

When a potential astrophysical neutrino is detected by IceCube, an alert with the reconstructed coordinates is sent among others to MAGIC, where follow-up observations are performed in search of a correlated gamma-ray flux. As the MAGIC telescopes are designed to observe sources with well-known coordinates, the analysis for discovering sources in a given region has to be modified. Different statistical methods for identifying point sources as possible neutrino sources are studied. This talk presents an overview of different techniques of deriving sky maps for point source searches.
