X-Ray Emission from the Galactic Supernova Remnant G12.0-0.1

We present results of the Suzaku/XIS observation around the radio supernova remnant (SNR) G12.0-0.1. No significant diffuse emission extending in or along the radio shell was observed. Instead two compact X-ray sources, Suzaku J181205-1835 and Suzaku J181210-1842, were found in or near G12.0-0.1. Suzaku J181205-1835 is located at the northwest of the radio shell of G12.0-0.1. The X-ray profile is slightly extended over the point spread function of the Suzaku telescope. The X-ray spectrum has no line-like structure and is well represented by a power-law model with a photon index of 2.2 and an absorption column of N_{H}=4.9x10^{22} cm^{-2}. The distances of Suzaku J181205-1835 and G12.0-0.1 are estimated from the absorption column and the Sigma-D relation, respectively, and are nearly the same with each other. These results suggest that Suzaku J181205-1835 is a candidate of a pulsar wind nebula associated with G12.0-0.1. From its location, Suzaku J181210-1842 would be unrelated object to G12.0-0.1. The X-ray profile is point-like and the spectrum is thin thermal emission with Fe K-lines at 6.4, 6.7, and 6.97 keV, similar to those of cataclysmic variables.
