Özet
Observations conducted with H.E.S.S. at high energies have led to the discovery of numerous gamma-ray sources in the Galactic plane at TeV energies. One of these sources, HESS J1832–085, has been suggested to be a pulsar wind nebula (PWN); however, its nature is not yet fully understood. In this work, we analyze Suzaku data to investigate the X-ray spectral properties of HESS J1832–085. We found that the X-ray spectra are highly absorbed and well-represented by a power-law model with a photon index of Γ∼1.5, and an unabsorbed X-ray flux of FX∼0.3×10-11 erg cm−2 s−1 in the 2–10 keV energy band. The gamma-ray flux is approximately 66 times higher than the X-ray flux. Based on our X-ray analysis, we discuss the origin of the source HESS J1832–085. We propose that the PWN scenario is possible, although several issues still need to be resolved.
