Radio Galaxy 3C83.1B

This is a false-color image of the wide-angle radio galaxy 3C83.1B, associated with the elliptical galaxy NGC1265 in the Perseus Cluster of galaxies. Blue colors show the distribution of stars, made from an image from the Digitized Second Palomar Sky Survey, and red colors show the radio radiation as imaged by the VLA, measured at a wavelength of 20cm. The galaxy is moving through the intergalactic medium of the Perseus Cluster at a velocity of about 2000 km/s. It is thought that twin beams of plasma ejected from the galactic nucleus are bent by the ram pressure exerted by the external gas, producing the 'U' shape. The radio tail extends much further than is visible in this image.

Radio data: VLA C+D array L-band (20cm) observation, 12" resolution.
