1st Abstract

Recently, the SNR IC443 was detected at all nine Planck satellite frequencies (Planck Collaboration Int.@ XXXI 2016). The characteristic dip in emissivity between around 50 to 250 GHz is observed. It is proposed to be due to a break in the synchrotron power law resulting from the injection mechanism of the energetic particles, or due to cooling losses by the energetic particles. In this work, different emission models that can be responsible for the particular shape of IC443 SED are tested and discussed. The possibility of spinning dust emission signatures are emphasized.
