The Subparsec-Scale Structure and Evolution of Centaurus A: The Nearest Active Radio Galaxy

Abstract

We present high-resolution VLBI radio images of the closest classical radio galaxy, Centaurus A, including the highest resolution image yet for this source. The images were made from data obtained over a period of approximately 8 yr at the frequencies of 2. 3, 4.8, and 8.4 GHz with the Southern Hemisphere VLBI Experiment (SHEVE) array and at 2.3, 8.4, and 22.2 GHz with the Very Long Baseline Array. We give complete details of the data reduction and analysis procedures.
