Energy-dependent electron escape in evolving supernova remnants produces log-parabola distributions whose photon spectra are consistent with observations of RX J1713.7-3946 and SN 1006.
Simultaneous NICER+NuSTAR spectra of four TeV blazars show that 6 spectra require a blackbody component interpreted as accretion disk emission during low-flux states, plus Gaussian features at 1.4–1.7 keV in Mrk 421.
X-ray spectra of PG 1553+113 over 23 years are best described by log-parabola models in 14 cases and power-laws in 15, with synchrotron peaks indicating variable particle acceleration or cooling in the jet.
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.
