An X-ray compact source was discovered with Chandra in a supernova remnant ( SNR ) N23 , located in the Large Magellanic Cloud .
The compact source ( CXOU J050552.3 - 680141 ) is seen in only the hard band ( > 2 keV ) image of N23 , while the soft band image ( < 2 keV ) shows diffuse emission of the SNR , with an extent of \sim 60 \arcsec \times 80 \arcsec .
The compact source is located at almost the center of N23 , and there is no identifiable object for the source from previous observations at any other wavelength .
The source spectrum is best explained by a power-law model with a photon index of \Gamma = 2.2 ^ { +0.5 } _ { -0.3 } and an absorption-corrected luminosity of L _ { x } = 1.0 \times 10 ^ { 34 } ergs s ^ { -1 } in the 0.5–10 keV band for a distance of 50 kpc .
Neither pulsation nor time variability of the source was detected with this observation with a time resolution of 3.2 sec .
These results correspond with those of Hughes et al .
( 30 ) , who carried out analysis independently around the same time as our work .

Based on information from the best-fit power-law model , we suggest that the source emission is most likely from a rotation-powered pulsar and/or a pulsar wind nebula .
It is generally inferred that the progenitor of N23 is a core-collapsed massive star .
