VLA OBSERVATIONS AT RADIO WAVELENGTHS > E. B. Fomalont (email@example.com) K. I. Kellermann (firstname.lastname@example.org) R. B. Partridge (email@example.com) E. Richards (firstname.lastname@example.org) R. A. Windhorst (email@example.com) We are making a deep image of the HDF at 3.6 cm wavelength using the VLA in its C configuration, which provides an angular resolution of about 3 arcsec. Observations began in early February and will continue through March. The VLA field of view (nearly 9 arcmin in diameter) covers the entire HDF and most of the flanking fields. We plan additional observations at the same wavelength with the VLA in its D configuration. The data, when combined with the C-configuration data, will produce images at about 6 arcsec resolution and with an rms noise of 1.7 microJy. We also plan high resolution, A-configuration observations at both 3.6 cm (to provide 0.35 arcsec resolution) and 20 cm (to yield radio spectral indices). On the basis of earlier work on another HST field (Nature, 375, 471 ), we expect to detect 50-60 of the optically visible sources in the HDF and its flanking fields. Of these, virtually all are likely to be identified with optical objects. Our images will be made available on the Internet.
