Relic Radio Emission in 3C 388

New VLA images of the radio galaxy 3C 388 have revealed an intriguing distribution of spectral indices which is quite different from that of typical classical double sources. We observe two distinct regions of emission separated by a well-defined transition layer delineated by a dramatic jump. in the spectral index, particularly in the eastern lobe. We interpret these data as evidence of at least two distinct epochs of jet activity in which the current jets have resumed penetration of the IGM and are inflating younger, more energetic lobes into the relic lobes of the previous epoch. To the best of our knowledge, 3C 388 is the first radio galaxy in which multiple epochs of activity are clearly visible in the large-scale radio structure.
