22 Dec 2003 | | Subject: | astro-ph | | Affiliation: | 1,2), Patrick Slane , and Sangwook Park ( Rutgers University, University of Chicago, Harvard-Smithsonian CfA, Pennsylvania State University | | Abstract: | We report the discovery of pulsed X-ray emission from the compact object CXOU J112439.1-591620 within the Galactic supernova remnant G292.0+1.8 using the High Resolution Camera on the Chandra X-Ray Observatory. The X-ray period is consistent with the extrapolation of the radio period and spindown rate of PSR J1124-5916. The X-ray pulse is single peaked and broad. There is no optical counterpart to a limit of M_V ~ 26. The pressure in the pulsar wind nebula is considerably less than that in the reverse-shock-heated ejecta and circumstellar medium, indicating that the reverse shock has not yet begun to interact with the nebula. | | Source: | arXiv, astro-ph/0401472 | | Services: | Forum | Review | PDF | Favorites | |
