X-Ray Emission Associated with the Jet in 3C 273

The Einstein Observatory exposure of 3C 273 obtained with the High Resolution Imager has been re-analyzed using a subtraction technique. This technique is useful for studying weak features close to strong, unresolved sources. An X-ray feature located in PA = 222 deg has been isolated at a distance of 15.8 arcsec from the core. This is closer to the core than are the brightest optical and radio features. Some physical constraints for various possible emission mechanisms are given.
