Neutral hydrogen absorption at milliarcsecond resolutions: The radio galaxy 3C293
R. J. Beswick, A. B. Peck, G. B. Taylor +2
We present new milliarcsecond resolution observations of the H1 absorption against the kiloparsec scale inner jet of the radio galaxy 3C293. Using a combination of observations obt…
Parsec scale properties of nearby BL Lacs
M. Giroletti, G. Giovannini, G. B. Taylor +1
We present new radio data completing the imaging for a sample of 30 nearby (z < 0.2) BL Lac objects on parsec and kiloparsec scale. The sample is composed of both high and low lumi…
Active Galaxies at Milliarcsecond Resolution in the NOAO Deep Wide-Field Survey
J. M. Wrobel, T. A. Rector, G. B. Taylor +2
We are using the NRAO VLBA at 5.0 GHz to image about 200 FIRST sources stronger than 10 mJy at 1.4 GHz in the NDWFS.
Radio Observations of Nearby HST BL Lacs
M. Giroletti, G. Giovannini, G. B. Taylor +1
We present a radio/optical study of a sample of BL Lac objects at arcsecond and milliarcsecond resolution. The sample consists of 30 nearby (z<0.2) BL Lacs, mostly X-ray selected.…
Motion Statistics in the CJ Survey -- The Status in October 2002
R. C. Vermeulen, S. Britzen, G. B. Taylor +4
In the Caltech-Jodrell Survey of bright flat-spectrum radio sources, 3-5 epochs have now been observed for nearly all 293 sources; a uniquely large sample. The derivation of compon…
Magnetic Fields in Clusters of Galaxies Obtained Through the Study of Faraday Rotation Measures
F. Govoni, L. Feretti, M. Murgia +3
We are developing a new approach to investigate cluster magnetic field strengths and structures. It is based on the comparison of simulated Rotation Measure and radio halo images,…
