Deep Extragalactic VLBI-Optical Survey (DEVOS) II. Efficient VLBI detection of SDSS quasars
S. Frey, L. I. Gurvits, Z. Paragi +3
Context: The Deep Extragalactic VLBI-Optical Survey (DEVOS) aims at constructing a large sample of compact radio sources up to two orders of magnitude fainter than those studied in…
The Statistical Properties Of The Very Weak Radio Source Population In The GOODS/ACS HDF-N Region
T. W. B. Muxlow, R. J. Beswick, H. Thrall +3
Deep combination radio observations at 1.4GHz with the VLA and MERLIN have imaged a region 10 arcminutes square surrounding the Hubble Deep Field North (HDF-N). Initial studies of…
AGN and starbursts at high redshift: High resolution EVN radio observations of the Hubble Deep Field
M. A. Garrett, T. W. B. Muxlow, S. T. Garrington
We present deep, wide-field European VLBI Network (EVN) 1.6 GHz observations of the Hubble Deep Field (HDF) region with a resolution of 0.025 arcseconds. Above the 210 microJy/beam…
A high-resolution multi-wavelength study of the jet in 3C 273
S. Jester, H. -J. Roeser, K. Meisenheimer +2
We present HST images at 622 nm and 300 nm of the optical jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet. We find no evidence for localized…
Radio supernovae, supernova remnants and HII regions in NGC 2146 observed with MERLIN and the VLA
A. Tarchi, N. Neininger, A. Greve +5
We present a high-resolution 5-GHz radio continuum map of the starburst galaxy NGC 2146 made with MERLIN and the VLA, in a search of radio supernovae and supernova remnants expecte…
A MERLIN and VLBI Survey of Faint Compact Radio Sources
M. A. Garrett, Simon T. Garrington
We have selected a field from the VLA FIRST Survey which is typical in all aspects except one: it contains a bright, but extremely compact VLBI calibrator - J1159+291. 127 unresolv…
