摘要
The Galactic gamma-ray source HESS J1838-069 was discovered with H.E.S.S. in the 2004 galactic plane survey. The source is extended and is among the brightest H.E.S.S. survey sources. To identify the nature of this source, its central part was observed by the Chandra X-ray Observatory. The morphological and spectral characteristics of two possible counterparts, AX J1838.0-0655 and AX J1837.3-0652, are presented here. From the morphology and spectra, both sources are combatible with pulsar wind nebula scenarios. However, because of the high absorption column, the nebula around AX J1838.0-0655 might also be explained by a scattering halo around the central point source. We compare the Chandra data to expectations in this scenario.
