On the observation of the supernova remnant IC443 with the HAWC Observatory
Abstract
The supernova remnant IC 443 is one of the most thoroughly studied, and one of the clearest examples of interaction with molecular clouds. We present the observations of IC 433 in the multi-TeV energy range using data from the High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. IC 443 is significantly observed in the 1128 days of live-time of HAWC, ranging from November 26, 2014 to April 24, 2018, with a test statistics of 32.3 in the point-source search. The measured spectrum continues beyond 2 TeV, the maximum energy previously observed by VERITAS and MAGIC, with a photon index consistent with previous measurements. Results are presented in the context of existing models for gamma-ray production in IC 443.
