Chandra imaging of the gamma-ray source GeV J1809-2327.

Abstract (from CDS):

We report on Chandra imaging observations of the Galactic unidentified γ-ray source GeV J1809-2327, comparing the X-ray images with new VLA 1.46 and 4.86 GHz maps. The X-ray images reveal a point source connected to a nonthermal X-ray/radio nebula, supporting a pulsar/wind model for the γ-ray emitter. We also detect numerous X-ray sources from the young stellar association in the adjacent H II region S32.
