Observations of the γ-ray pulsar J1932+1916 in X-rays

We present the analysis of the archival Suzaku and Swift X-ray observations of the young γ-ray pulsar J1932+1916 field. The data revealed a point-like object at the γ-ray position of the pulsar and diffuse X-ray emission around it. Spectra of the point-like source and diffuse emission are well-described by absorbed power-law models with spectral parameters typical for pulsar plus pulsar wind nebula systems. Therefore, we suggest that Suzaku and Swift detected the X-ray counterpart of PSR J1932+1916. Assuming this interpretation, we constrain the distance to the pulsar in the range of 2–6 kpc. We also suggest possible association of the pulsar with the nearby supernova remnant G54.4–0.3 and discuss its implications for the pulsar proper motion, age and distance.
