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. Investigator(s): F. Yusef-Zadeh, M.R Morris, D.R. Chance This image is available in the following downloadable versions:
