We present the analysis result of the TeV unidentified source HESS J1702-420 with Suzaku. Inspite of the large flux of F(sub TeV) = 3.1 x 10(exp -11) ergs s(exp -1) cm(exp -2) in the 1-10 TeV band, X-ray counterpart was not detected even with deep exposure. The X-rays in this observation contain cosmic X-ray background (CXB) and Galactic ridge X-ray emission (GRXE) in addtion to the intrinsic emission of HESS J1702-420. To separate these components, we searched archive observation data whose Galactic latitude, on which GRXE depends, is near to that of HESS J1702-420. The data of HESS J1616-508 and its backgdound region were adopted. We assumued the CXB+GRXE component of HESS J1702-420 data is same as that of HESS J1616-508 data. We estimated the upper limit of the intrinsic flux from HESS J1702-420 as F(sub X) < 9.8 x 10(exp -13) ergs s(exp -1) cm(-2) in the 2-10 keV band for an assumed power-law of gamma = 2.1. If the TeV emission were originated from the Compton up-scattered cosmic microwave background (CMB) by high energy electrons, the low X-ray flux indicates weak magnetic field less than approximately 0.5 micro G, which is significantly smaller than the typical value in the Galactic plane of 3-10 micro G. Thus the TeV emission is likely originated from the high energy protons. |
