The population of compact radio sources in ONC

DOI

We present a deep centimeter-wavelength catalog of the Orion Nebula Cluster (ONC), based on a 30hr single-pointing observation with the Karl G. Jansky Very Large Array in its high-resolution A-configuration using two 1GHz bands centered at 4.7 and 7.3GHz. A total of 556 compact sources were detected in a map with a nominal rms noise of 3{mu}Jy/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.
