英文摘要We present X-ray observations of pulsar wind nebula (PWN) G16.73+0.08/supernova remnant (SNR) G16.7+0.1 using archival data of Chandra ACIS. The X-ray emission peak location of this PWN is found to be offset by 24 arcsec from the centre of the 1.4-GHz emission of this nebula. The X-ray nebula is elongated in the direction from the X-ray peak to the 1.4-GHz emission centre. This offset suggests that G16.73+0.08 is an evolved PWN interacting with the SNR reverse shock. We identify a point source, CXOJ182058.16-142001.5, near the location of the X-ray peak. The spectrum of the X-ray nebula can be described by an absorbed power law of photon index 0.98(-0.71)(+0.79) and hydrogen column density N-H = 4.99(-2.28)(+2.75) x 10(22) cm(-2). CXO J182058.16 - 142001.5 is likely a pulsar. We estimate its spin-down power to be about 2.6 x 10(36) erg s(-1). Assuming its age at 3000 and 10 000 yr, its dipole magnetic field strength at the polar surface is estimated to be about 4.2 x 10(13) and 1.3 x 10(13) G, respectively.
