We present an update on our ongoing multiwavelength program to study high energy emission from extragalactic jets. We have selected several systems from our Chandra snapshot survey (Marshall et al. 2005, Marshall et al. in prep) for detailed follow-up study. Of particular interest are Chandra and Magellan observations of PKS 1421-490 (scheduled in April and May of this year, respectively). In this system we discovered an unusual feature 5.9" from the core that can only be described as either a unique, optically-dominated jet knot or as an extremely unlikely chance alignment of a new type of radio-quiet BL Lac object (Gelbord et al 2005). We also report recent Chandra and HST observations of PKS 2101-490. The jet of this system has a total length of 12" (=97 kpc in the plane of the sky at z=1.04). X-rays are found throughout this length despite a bend of 35 degrees 7.5" from the core.
Partial support for this work was provided by the NASA through the SAO contract SV3-73016 to MIT for Support of the Chandra X-Ray Center, which is operated by SAO for and on behalf of NASA under contract NAS8-03060. Support has also come from SAO grant GO4-5124 and directly from NASA under contract NAS8-39073.
