Significance maps for HAWC’s > 56 TeV emission and its comparison to the SNR and molecular clouds in the region. a) The HAWC significance map of the region above 56 TeV. b) The brightness temperature image (Taylor et al. 2003) of the SNR overlaid with the HAWC 3, 4, and 5σ contours in white. c) Molecular hydrogen column density integrated over a velocity range of −20 km/s to 0 km/s (Dame et al. 2001). d) The Planck 353 GHz template normalized to 1/sr that is used in the UHE HAWC fit.
