Is there a PeVatron hiding inside HESS J1702-420questionMark

HESS J1702420 is a PeVatron candidate without multiwavelength associations.The identification of active PeVatrons, CR accelerators reaching the knee (few10^15 eV), is key to understand the origin of CRs in the Galaxy. With deepobservations and improved analysis, H.E.S.S. has recently found a new compactsource, hidden under the bulk emission of HESS J1702420. Its straight and veryhard powerlaw spectrum, extending up to 100 TeV, makes it a very solid PeVatroncandidate. Remarkably, Suzaku has detected, with large uncertainties, an Xraysource very close to the new compact TeV source. These facts, together with thediscovery of energydependent shrinking of HESS J1702420 towards the new TeVsource, call for a deep XMM observation to investigate a PWN scenario. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
