Detection of a Compact Nuclear Radio Source in the Local Group
  Elliptical Galaxy M32
  The Local Group compact elliptical galaxy M32 hosts one of the nearest
candidate super-massive black holes (SMBHs), which has a previously suggested
X-ray counterpart. Based on sensitive observations taken with the {\it Karl G.
Jansky} Very Large Array (VLA), we detect for the first time a compact radio
source coincident with the nucleus of M32, which exhibits an integrated flux
density of $\sim$$47.3\pm6.1$ $\mu$Jy at 6.6 GHz. We discuss several
possibilities for the nature of this source, favoring an origin of the
long-sought radio emission from the central SMBH, for which we also revisit the
X-ray properties based on recently acquired {\sl Chandra} and {\sl XMM-Newton}
data. Our VLA observations also discover radio emission from three previously
known optical planetary nebulae in the inner region of M32.
