We present Chandra, XMM-Newton, and Rossi X-Ray Timing Explorer observations of 1WGA J1713.4-3949, a compact source at the center of the Galactic supernova remnant (SNR) G347.3-0.5. The X-ray spectrum of the source is well fitted by the sum of a blackbody component with a temperature of ∼0.4 keV plus a power-law component with a photon index of ∼4. We found no pulsations down to 4% in the 0.01-0.16 Hz range nor down to 25% in the 0.01-128 Hz range. This source resembles other compact central objects in SNRs, and we suggest that 1WGA J1713.4-3949 is the associated neutron star for G347.3-0.5. We also measured the properties of the adjacent radio pulsar PSR J1713-3945 with a 392 ms period, and we show that it is not associated with 1WGA J1713.4-3949 nor, most probably, is it associated with SNR G347.3-0.5.
