IceCube Search for Galactic Neutrino Sources based on HAWC - PowerPoint PPT Presentation

IceCube Search for Galactic Neutrino Sources based on HAWC Observations of the Milky Way Ali Kheirandish TAUP 2019, Toyama, Japan

Galactic Cosmic Ray Accelerators • The search for Galactic cosmic neutrino sources concentrates on the search for “ Pevatrons ” which have the required energetics to produce cosmic rays up to the knee in the spectrum. • “Pevatrons” will produce pionic 𝛿 -rays whose spectrum extends to several hundred TeV without cut-off. • Supernova remnant meet these condition. • TeV 𝛿 -rays should be accompanied by TeV neutrinos, observable by IceCube. π ± ν Galactic Extragalactic [PDG 2018] � 2

Galactic Plane at High Energies Galactic plane in 10 TeV gamma rays Sources were identified in the initial map of Southern Milagro that were the Hemisphere most significant Sky sources after Crab. The idea was to look for supernova remnants in star forming regions. [Milagro] [Halzen+2008] • Early predictions: IceCube should Neutrino spectra for all sources observe sources after 5 years. � 3 [Beacom+2007, Halzen+2008, Gonzalez-Garcia+2009]
