cds-question@unistra.frx-ray-sourcesradio-sourcesWe investigate the relationship between faint X-ray and 1.4GHz radio source populations detected within 3' of the Hubble Deep Field (North) using the 1Ms Chandra (Cat. <J/AJ/122/2810>) and 40{mu}Jy VLA (Cat. <J/ApJ/533/611>) surveys. Within this region, we find that ~42% of the 62 X-ray sources have radio counterparts and ~71% of the 28 radio sources have X-ray counterparts; thus, a 40{mu}Jy VLA survey at 1.4GHz appears to be well matched to a 1Ms Chandra observation.2002AJ....124.2351Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/124/2351CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/533/611 : 1.4GHz survey in HDF region (Richards+, 2000)J/ApJ/554/742 : Chandra Deep Survey of the HDF-N (Hornschemeier+, 2001)J/AJ/122/2810 : Chandra Deep Field North Survey.
