We present new deep, high-resolution, 1.5 GHz observations of theprototypical nearby Perseus galaxy cluster from the Karl G. Jansky Very LargeArray. We isolate for the first time the complete tail of radio emission of thebent-jet radio galaxy NGC 1272, which had been previously mistaken to be partof the radio mini-halo. The possibility that diffuse radio galaxy emissioncontributes to mini-halo emission may be a general phenomenon in relaxedcool-core clusters, and should be explored. The collimated jets of NGC 1272initially bend to the west, and then transition eastward into faint, 60kpc-long extensions with eddy-like structures and filaments. We suggestinterpretations for these structures that involve bulk motions of intraclustergas, the galaxy's orbit in the cluster including projection effects, and thepassage of the galaxy through a sloshing cold front. Instabilities andturbulence created at the surface of this cold front and in the turbulent wakeof the infalling host galaxy most likely play a role in the formation of theobserved structures. We also discover a series of faint rings, south-east ofNGC 1272, which are a type of structure that has never been seen before ingalaxy clusters.
