Searches for Extended and Point-like Neutrino Sources with Four Years of IceCube Data

Understand

We present results on searches for point-like sources of neutrinos using four years of IceCube data, including the first year of data from the completed 86-string detector.

• The total livetime of the combined dataset is 1,373 days.
• For an E$^{-2}$ spectrum the median sensitivity at 90\% C.L.
• is $\sim 10^{-12}$ TeV$^{-1}$cm$^{-2}$s$^{-1}$ for energies between 1 TeV$-$1 PeV in the northern sky and $\sim 10^{-11}$ TeV$^{-1}$cm$^{-2}$s$^{-1}$ for energies between 100 TeV $-$ 100 PeV in the southern sky.
