An optical-infrared JET in 3C 133

We report the discovery of a new optical-IR synchrotron jet in the radio galaxy 3C 133 from our HST NICMOS snapshot survey. The jet and eastern hot spot are well resolved and visible at both optical and IR wavelengths. The IR jet follows the morphology of the inner part of the radio jet, with three distinct knots identified with features in the radio. The radio-IR SEDs of the knots are examined, along with those of two more distant hot spots at the eastern extreme of the radio feature. The detected emission appears to be synchrotron, with peaks in the NIR for all except one case, which exhibits a power-law spectrum throughout.
