The paper presents a conceptual design for a stacked focal-plane polarimeter using multilayer mirrors, imaging photoelectric detectors, and an active Compton polarimeter to extend X-ray polarimetry to tens of keV with improved sensitivity.
New IXPE X-ray polarimetry and optical monitoring of PG 1553+113 reveal variable polarization and a large EVPA swing, supporting jet models with related but non-co-spatial X-ray and optical emission regions.
First results from the SPOTS campaign reveal low average optical polarization (≲10%) and low magnetic field ordering (F_B ≲0.10) across 14 TeV blazars, with stochastic or rotating polarization angles and wavelength-dependent behavior indicating complex, turbulent jet structures.
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.
