Galactic Fine Structure at 843 MHz

Abstract

The Southern Galactic Plane surveyed by the Molonglo Observatory Synthesis Telescope (MOST) gives an unprecedented view of fine-scale structure in low frequency radio continuum emission over the area 245° ≤ l ≤ 355°, |b| ≤ 1.5°. The telescope operates at 843 MHz with a resolution of 43″ and a sensitivity of approximately 2 mJy/beam for the sample region (5° × 3°), centred on G317.5+0.0, presented here to illustrate significant features in the sources. This is a mosaic of 35 fields, each representing a 12 hr observation.
