These discoveries marked a significant paradigm shift in high-energy astrophysics and astroparticle physics from &#8220;Do PeVatrons exist in our galaxy?&#8221; to &#8220;What are the Galactic PeVatrons?&#8221; As highlighted in previous studies of Galactic TeV sources, multi-wavelength observations play a crucial role in identifying PeVatrons and particle acceleration mechanisms, for example, by characterizing synchrotron emission from primary and secondary TeV-PeV electrons. In particular, a combination of broadband spectral energy distribution (SED) and morphological data in the X-ray and TeV bands is a powerful tool for probing their particle acceleration and emission mechanisms. This presentation will review the latest multi-wavelength studies of Galactic PeVatron candidates, primarily focusing on X-ray observations in conjunction with radio, GeV, and TeV data. Key topics include: (1) multi-epoch NuSTAR hard X-ray observations of young supernova remnants, (2) multi-wavelength observations of pulsar wind nebulae associated with UHE sources, (3) X-ray investigations of new PeVatron classes (e.g., microquasar jets), (4) X-ray surveys of the Galactic Center, and (5) searches for X-ray counterparts of unidentified or \u201cdark\u201d Galactic PeVatrons. Finally, I will discuss the future prospects of X-ray astrophysics in advancing our understanding of Galactic PeVatrons.<\/td><\/tr><\/tbody><\/table><\/div><\/figure>\n","protected":false},"featured_media":0,"template":"","tag_year":[],"class_list":["post-16238","event_researcher","type-event_researcher","status-publish","hentry","en-US"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!--
