Relativistic Beaming and the Intrinsic Properties of Extragalactic Radio Jets
M. H. Cohen, M. L. Lister, D. C. Homan +4
Relations between the observed quantities for a beamed radio jet, apparent transverse speed and apparent luminosity (beta_app,L), and the intrinsic quantities, Lorentz factor and i…
HI absorption in 3C 49 and 3C 268.3. Probing the environment of Compact Steep Spectrum and GHz Peaked Spectrum sources
A. Labiano, R. C. Vermeulen, P. D. Barthel +4
We present and discuss European VLBI Network UHF band spectral line observations, made to localise the redshifted 21cm HI absorption known to occur in the subgalactic sized compact…
Atomic hydrogen in the one-sided "compact double" radio galaxy 2050+364
R. C. Vermeulen, A. Labiano, P. D. Barthel +3
European VLBI Network spectral imaging of the "compact double" radio source 2050+364 in the UHF band at 1049 MHz has resolved the HI absorbing region, and has shown a faint continu…
Sub-milliarcsecond Imaging of Quasars and Active Galactic Nuclei. IV. Fine Scale Structure
Y. Y. Kovalev, K. I. Kellermann, M. L. Lister +11
We have used VLBA fringe visibility data obtained at 15 GHz to examine the compact structure in 250 extragalactic radio sources. For 171 sources in our sample, more than half of th…
The Presence and Distribution of HI Absorbing Gas in Sub-galactic Sized Radio Sources
Y. M. Pihlstroem, J. E. Conway, R. C. Vermeulen
We consider the incidence of HI absorption in intrinsically small sub-galactic sized extragalactic sources selected from sources classified as Gigahertz Peaked Spectrum (GPS) and C…
Observations of HI Absorbing Gas in Compact Radio Sources at Cosmological Redshifts
R. C. Vermeulen, Y. M. Pihlstroem, W. Tschager +12
We present an overview of the occurrence and properties of atomic gas associated with compact radio sources at redshifts up to z=0.85. Searches for HI 21cm absorption were made wit…
