Suzaku hard X-ray observations of HESS J1813-178
Abstract
Radio and X-ray observations towards the VHE gamma-ray source HESS J1813-178, initially dubbed as a ``dark accelerator,'' suggested its association with the SNR G12.8-0.0. Subsequent XMM and Chandra observations confirmed earlier ASCA findings of an extended, center-filled X-ray source, not resembling the contours of the radio-detected supernova remnant (SNR). Morphological and spectral resemblance of the X-ray emission seen at the center of the shell of SNR G12.8-0.0 with a Pulsar Wind Nebula (PWN) suggest HESS J1813-178 is one of the increasing number of objects classified as ``composite SNR.'' In March 2007, 65 ksec Suzaku observations were taken, and we are able to confirm the previously reported characteristics of the X-ray counterpart from HESS J1813-178 as a diffuse hard X-ray source central to the radio-shell of SNR G12.8-0.0.
