How multiwavelength datasets aid in galaxy evolution studies

In an effort to better understand the chemical and dynamical history of galaxies as members of larger structures (e.g., groups, clusters, and filaments), synthesis of multiwavelength data often provides supportive lines of inference and opportunities for integration. Specifically, examination of non-optical emission at X-ray and radio wavelengths supplements traditional optical imaging with dynamical context to the galaxy histories. As an example of multiwavelength analysis, I will present the case for significant galaxy pre-processing within a group environment at low redshift (z~0.05). The X-ray and radio wavelengths are crucial to the argument that the group is recently infalling (< 1 Gyr) and not homogeneous with the cluster galaxies.
