Scientific paper

We present archival data from the Chandra X-Ray Observatory that reveal a bright point source to the southeast of the center of the young supernova remnant G292.0+1.8 that is coincident with the peak of highest radio surface brightness. The mostly featureless spectrum of the point source at coordinates (J2000) RA = 11 24 39.2, DEC = -59 16 19.8 is well fit by a three-parameter absorbed model with one power-law and two blackbody components. We also argue that the neutron star is surrounded by a synchrotron wind nebula based off of the source's hard emission and high radio and X-ray luminosities, each corresponding to a canonical wind nebula spin-down power, dE/dt ~ 10^36 erg/s.
