The X-ray source SLX 1744-299 is located near the Galactic center. Before ROSAT, the weak source at the top was obscured by the brighter double source. With ROSAT, this soft source which forms the "head" of the "Mouse," (a radio source named for its unusual form), is discernable. SLX 1744-299 is likely a quickly moving pulsar which leaves a "wake" of relativistic electrons which interact with the magnetic field to generate the synchrotron radio emission.
