Abstract:
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° XMMNewton/ROSAT X-ray Survey Area. 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.
