Abstract (from CDS):

We report the discovery of 31.18 ms pulsations from the INTEGRAL source IGR J14003-6326 using the Rossi X-ray Timing Explorer (RXTE). This pulsar is most likely associated with the bright Chandra X-ray point source lying at the center of G310.6-1.6, a previously unrecognized Galactic composite supernova remnant (SNR) with a bright central non-thermal radio and X-ray nebula, taken to be the pulsar wind nebula (PWN). PSR J1400-6325 is amongst the most energetic rotation-powered pulsars in the Galaxy, with a spin-down luminosity of {dot}E = 5.1 ×10^37 erg/s. In the rotating dipole model, the surface dipole magnetic field strength is Bs= 1.1 x 1012 G and the characteristic age τ_ c ≡P/2{dot}P = 12.7 kyr. The high spin-down power is consistent with the hard spectral indices of the pulsar and the nebula of 1.22±0.15 and 1.83±0.08, respectively, and a 2-10 keV flux ratio FPWN/FPSR∼ 8. Follow-up Parkes observations resulted in the detection of radio emission at 10 and 20 cm from PSR J1400-6325 at a dispersion measure of ∼560/cm3 pc, which implies a relatively large distance of 10±3 kpc. However, the resulting location off the Galactic plane of ∼280 pc would be much larger than the typical thickness of the molecular disk, and we argue that G310.6-1.6 lies at a distance of ∼7 kpc. There is no gamma-ray counterpart to the nebula or pulsar in the Fermi data published so far. A multi-wavelength study of this new composite SNR, from radio to very high-energy gamma rays, suggests a young (≲103 yr) system formed by a sub-energetic (≲1050 erg), low ejecta mass (Mej∼ 3 M) supernova explosion that occurred in a low-density environment (n0∼ 0.01/cm3).
