Radio Milli-Halo in the Nucleus of NGC 1275

We present high dynamic range VLBA observations of 3C 84 at 1414 MHz, 612 MHz, and 330 MHz. With these observations, we have discovered a previously undetected component that is centered 60 mas to the north of the compact core and has a diameter of 90 mas. We have also discovered the first halo around an Active Galactic Nucleus on small (< 1 kpc) scales. The milli-halo emits synchrotron radiation, which suggests the possibility of a new luminosity source near the centers of compact cores.
