Abstract

42 hours of A-array VLA data and 18 days MERLIN data at 1.4GHz have been combined to image a 10 arcminute field centred on the Hubble Deep Field. This area encloses both the Hubble Deep and Flanking Fields. A complete sample of 91 sources have been detected with flux densities above 40 μJy. All these have been imaged with the MERLIN+VLA combination to produce images with 0.2, 0.3 and 0.5 arcsecond resolution. These are the most sensitive 1.4GHz images yet made with rms noise levels of 3.3 μJy/beam in the 0.2 arcsecond images. About 70% of the microJy sources are found to be starburst type systems associated with major disk galaxies in the redshift range 0.4 - 1. Some 20% are found to be low-luminosity AGN systems identified with field ellipticals at redshifts close to 1. The remaining 10% are associated with optically faint systems close to or beyond the HDF limit; many of these may be dust-shrouded starbursts at high redshift. Recent wide-field EVN observations of the HDF (Garrett et al, these procs.) confirm that one of these objects (J123642+621331) is probably a dust enshrouded starburst system at z=4.424 with an embedded AGN.
