3C353 is the fourth strongest radio galaxy in the 3C Catalogue (flux density 57 Jy at 1.4 GHz). The host is a V=15.4-magn elliptical galaxy at z = 0.0304, the dominant member of a Zwicky cluster.
3C353's projected linear size is 120 kpc, and its monochromatic luminosity P1.4 GHz is ~ 5h -2 × 1025 W Hz-1 for H0 = 100h km s-1 Mpc-1.
The source contains a well-collimated jet and counterjet (Swain, Bridle, & Baum 1996), differing by a factor of ~ 2 in integrated flux density, and together comprising 1% of the total emission.
The lobe morphology, the clear hot spot in the jetted lobe, and the source's position in the bivariate optical-radio luminosity domain (Owen & Ledlow 1994), are all consistent with classifying 3C353 as an FR Type II source (Fanaroff & Riley 1974).
We report VLA 8.4-GHz imaging of the total and polarized emission of 3C353 that shows the internal structure of kpc-scale jets in this FRII source at unusually high spatial resolution (FWHM 185 pc in projection). We also present a simple model for this structure.
