This source is one of the highest-energy known gamma-ray sources, with emission extending past 200 TeV. Modeling suggests that the bulk of the TeV gamma-ray emission is leptonic in nature, driven by the energetic radio-faint pulsar PSR J1907+0602. Depending on what assumptions are included in the model, a hadronic component may also be allowed. Using the results of the modeling, we discuss implications for detection prospects by multi-messenger campaigns. %R 10.3847/1538-4357/ac56e5 %U https://arxiv.org/abs/2112.00674 %U https://doi.org/10.3847/1538-4357/ac56e5 %P 116-13pp
