The Population of Compact Radio Sources in the Orion Nebula Cluster
  We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster
(ONC), based on a 30h single-pointing observation with the Karl G. Jansky Very
Large Array in its high-resolution A-configuration using two 1 GHz bands
centered at 4.7 GHz and 7.3 GHz. A total of 556 compact sources were detected
in a map with a nominal rms noise of 3 muJy/bm, limited by complex source
structure and the primary beam response. Compared to previous catalogs, our
detections increase the sample of known compact radio sources in the ONC by
more than a factor of seven. The new data show complex emission on a wide range
of spatial scales. Following a preliminary correction for the wideband
primary-beam response, we determine radio spectral indices for 170 sources
whose index uncertainties are less than +/-0.5. We compare the radio to the
X-ray and near-infrared point-source populations, noting similarities and
differences.
