Source Classification:
From Martin et al. (2016):
- "We estimate the molecular mass around CTA 1 using data from Planck
and the Harvard CO survey. We observe that the molecular mass in the
vicinity of the complex is not enough to explain the TeV emission
observed by VERITAS, even under favorable assumptions for the
cosmic-ray acceleration properties of the supernova remnant. This
supports the idea that the TeV emission comes from the PWN. "
From Acero et al. (2013):
- This LAT emission from this source below 10 GeV is likely from a
