13+38 XMM-Newton/ROSAT 1.4GHz radio catalog
Listed in IVOA Registry (Virtual Observatory)
In order to determine the relationship between the faint X-ray and faint radio source populations, and hence to help understand the X-ray and radio emission mechanisms in those faint source populations, we have made a deep 1.4-GHz Very Large Array radio survey of the 13h+38{deg} XMMNewton/ROSAT X-ray Survey Area.
Description
From a combined data set of 10-h, B-configuration data and 14-h, A-configuration data, maps with 3.35-arcsec resolution and a noise limit of 7.5Jy were constructed.
A complete sample of 449 sources was detected within a 30-arcmin diameter region above a 4 detection limit of 30Jy, at the map centre, making this one of the deepest radio surveys at this frequency. The differential source count shows a significant upturn at submilliJansky flux densities, similar to that seen in other deep surveys at 1.4GHz (e.g. the Phoenix survey, Cat. <J/MNRAS/296/839>), but larger than that seen in the Hubble Deep Field (HDF) which may have been selected to be underdense.

This upturn is well modelled by the emergence of a population of medium-redshift star-forming galaxies which dominate at faint flux densities. The brighter source counts are well modelled by active galactic nuclei.
