Abstract:

Extreme HBL objects are BL Lac objects characterized by their hard TeV gamma-ray spectra, by which the sources are considered as excellent targets to study secondary cascade gamma-ray emission induced by very-high-energy photons or protons from the sources. We propose Suzaku observations of 1ES 0347-121 and KUV 00311-1938 for 60 ks and 40 ks, respectively. The observations can reveal detailed spectral structure around synchrotron peak in the extreme HBLs, which are essential to derive physical parameters such as electron spectrum, magnetic filed strength in the jet. The results will help understating gamma-ray components of both intrinsic jet emission and the secondary cascade emission.
