Message Received: Radio Observations in the Multi-Messenger Era. Nicole Lloyd-Ronning Los Alamos National Lab; University of New Mexico, Los Alamos Abstract: With the advent of gravitational wave detections from compact object mergers and the increasing number of cosmic neutrino detections (including the first potential association of a high energy neutrino with a blazar jet), we now can truly utilize multiple channels with which to observe and understand our universe. Our understanding will not be complete, however, without a coherent view of all of these "messages" - photons, neutrinos, cosmic rays, and gravitational waves. Radio observations are not only an important piece of this puzzle, but absolutely essential if we hope to truly decipher the physics behind a number of astrophysical sources - especially black holes/compact objects at all scales and their progenitors. In this talk, I will discuss how radio/mm observations from an ngVLA - particularly when coordinated with observations at other wavelengths - will enlighten our understanding of astrophysical objects that are multi-messenger in nature.
