X-Ray Observation of Very High Energy Gamma-Ray Source, HESS J1745-303, with Suzaku

Understand

Suzaku observations of a TeV unidentified (unID) source, HESS J1745-303, are presented.

• A possible excess of neutral iron line emission is discovered, and is likely associated with the main part of HESS J1745-303, named "region A".
• It may be an X-ray reflection nebula where the X-rays from previous Galactic Center (GC) activity are reflected by a molecular cloud.
• This result further strengthens the assumption that the molecular cloud which is spatially coincident with region A of HESS J1745-303 is located in the GC region.
