Description
The supernova remnant IC443 is a source of gamma rays. We report our observations of this region using data from the HAWC observatory. The results are consistent with previous very-high energy observations, showing a soft spectrum and no sign of a cutoff. Surprisingly, we also find a second component in the emission at these high energies that is extended and shows a hard spectrum with no evidence of a drop in the spectrum. The emission overlaps with the 90 kyr pulsar B0611+22. We conclude that this emission is a TeV Halo produced by this old pulsar.
