Radio SETI has focused on the discovery of narrowband signals and artificially dispersed broadband pulses from extraterrestrial worlds; in contrast to these technosignature morphologies, periodic spectral signals offer an energetically efficient means of transmission across vast interstellar distances; a rotating beacon at the Milky Way’s center is, in particular, advantageously placed for galaxy-wide communications.
