Multi-instrument observations reveal broad overlap in X-ray photon indices across blazar subclasses with intra-source spectral evolution supporting transition-like behavior.
Review assessing HSP BL Lacs as UHECR and neutrino sources, noting strains from baryonic loading, heavy-nuclei preference in Auger data, and isotropy mismatch with beamed sources.
