The SNR G106.3+2.7, with its associated molecular cloud complex, is one of the candidate TeV counterparts of LHAASO J2226+6057, one of the 12 sources detected by LHAASO at >100 TeV.
The other candidate is the Boomerang PWN, associated with the PSR J2229+6114. This VHE region has been detected by different 𝛾-ray facilities. It has an elongated morphology: the SNR is located in the “tail” of the VHE emission and the PWN is in the “head”. Identifying the exact location of the emission at > ∼ 100 TeV is a pivotal factor to distinguish between the hadronic or leptonic origin of the 𝛾-ray emission and to constrain the acceleration mechanism. The MAGIC telescopes resolved for the first time this TeV region, finding that 𝐸 > 10 TeV emission comes only from the tail region, where the SNR G106.3+2.7 resides. However, additional and more precise measurements are required to confirm these results.

In this context, the ASTRI Mini-Array can play a crucial role. Thanks to its performance in the multi-TeV band, this facility will make an essential contribution to understanding the nature of the UHE emission shedding light on its possible relation with CR origin.

Building on the latest important results reported by the MAGIC collaboration, this work aims at investigating the potential of ASTRI-MiniArray in studying the complex morphology of this source and showing the potential improvements which can be obtained thanks to deep observation of the source.
