Sagittarius A Radio Continuum

Description

The radio continuum observations of Sagittarius A (Sgr A) plus the continuum arc in the direction of Galactic Center at 20 cm. The most interesting result from our observations is the recognition of a system of narrow filamentary structures, which make up the continuum arc, having typical widths of 20 arc seconds (~ 1pc). These radio filaments are perpendicular to the galactic plane, parallel to each other, regular, unbroken and homogeneous in their appearance. The presence of a halo of 8 arcmin diameter (24 pcs) surrounding the Sgr A East shell can also be seen. This halo consists of a number of large scale protrusions directed perpendicular to the galactic plane.
Observing runs - 1982 September and 1983 May at the VLA in B- and C/D-configurations using 27 antennas.
