Narrow angle tail (NAT) radio galaxies offer intriguing hints as to the nature of the interaction of galaxies with the intra-cluster medium (ICM). They frequent areas of enhanced X-ray emission in clusters of galaxies; there are strong indications that ram pressure forces associated with merging subclusters bend the galaxies' jets. We propose to observe two NAT galaxies in the Perseus cluster, exploring their intrinsic X-ray emission and their interactions with the cluster gas. Chandra's arcsecond resolution will permit direct comparisons of X-ray and radio structures, the separation of galactic and ICM spectroscopic signatures, and probes of the effects of merging subclusters on NAT morphology, and thus the role of these galaxies as diagnostics of the underlying cluster substructure.
