X-ray observations of the new pulsar-supernova remnant system PSR J1119-6127 and supernova remnant G292.2-0.5.


Abstract (from CDS):

PSR J1119-6127 is a recently discovered 1600-yr-old radio pulsar that has a very high inferred surface dipolar magnetic field. We present a detailed analysis of a pointed ASCA observation and archival ROSAT data of PSR J1119-6127 and its surroundings. Both data sets reveal extended emission coincident with the newly discovered radio supernova remnant G292.2-0.5, which is reported in a companion paper by Crawford et al. A hard point source, offset ∼1'.5 from the position of the radio pulsar, is seen with the ASCA Gas Imaging Spectrometer (GIS). No pulsations are detected at the radio period with a pulsed fraction upper limit of 61% (95% confidence). The limited statistics prevent a detailed spectral analysis, although a power-law model with photon index Γ~1-2 describes the data well. Both the spectral model and derived X-ray luminosity are consistent with those measured for other young radio pulsars, although the spatial offset renders an identification of the source as the X-ray counterpart of the pulsar uncertain.
