Sagittarius A Arched Filament Complex
Description
This is a VLA 20 cm continuum image showing the central ~60 pc of the Galactic Center with the most prominent extended radio features shown: the linear, magnetic filaments in the Radio Arc, Northern and Southern Threads and G359.8+0.2, and the thermal Arched Filaments HII regions. The position of the extraordinary stellar cluster, the Arches cluster, is also noted and is thought to be responsible for the ionization of the Arched Filaments HII regions.
VLA DnC, CnB, BnA from Morris and Yusef Zadeh (1985-1987), supplemented with additional CnB data from 1989 reprocessed together, re-imaged using imagr in 1986. FOV: 25' x 30' or ~60 x 75 pc at the Galactic Center distance (8.0 kpc).
