Obscuration of the Parsec Scale Jets in the Compact Symmetric Object 1946 + 708

Abstract

We present results of VLA and VLBA observations of the 1.420 GHz neutral hydrogen absorption associated with the Compact Symmetric Object 1946+708 (z=0.101). We find significant structure in the gas on parsec scales. The peak column density in the H i (NHI ≃2.2×10 23 cm( Ts 8000K ) ) occurs toward the center of activity of the source, as does the highest… (More)
