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.…
Parsec Scale Properties of Radio Sources
G. Giovannini, M. Giroletti, G. B. Taylor +3
We present a new complete sample of radio sources selected from the B2 and 3CR catalogues, with no bias respect to the jet velocity and orientation. Using preliminary data we inves…
Global VLBI Observations of HI Absorption toward NGC 3894
A. B. Peck, G. B. Taylor
One of the most important problems in the study of AGN is understanding the detailed geometry, physics, and evolution of the central engines and their environments. The leading mod…
