High resolution observations of a selection of faint 1.4GHz radio counterparts to optical sources in the HDF-N

We present recent results from very deep MERLIN/VLA 1.4GHz observations of an 8.5-by-8.5 arcminute field centred on the the Hubble Deep Field North, in conjunction with BVIz catalogues of GOODS/ACS sources detected in this field. In an extension of work by Muxlow et al. (also presented at this conference) on the statistical properties of over 8000 sources, the results presented here take advantage of the deep (rms: 3.3 microJy/bm), sub-arcsecond radio imaging of this field to characterise the properties at 1.4GHz of a number of individual radio counterparts to GOODS/ACS sources.
