New 20-cm radio-continuum study of the small Magellanic cloud: Part I - Images

TL;DR

This paper presents high-resolution, high-sensitivity 20-cm radio-continuum images of the Small Magellanic Cloud, created by merging archival data, to facilitate future studies of its sources and structure.

Contribution

The paper introduces new, detailed radio-continuum images of the SMC by combining data from multiple telescopes, enhancing resolution and sensitivity.

Findings

Images cover resolutions from ~10'' to ~150''

Sensitivity achieved is r.m.s. >= 0.5 mJy/beam

Images will support future SMC research

Abstract

We present and discuss new high-sensitivity and resolution radio-continuum images of the Small Magellanic Cloud (SMC) at lambda=20 cm (nu=1.4 GHz). The new images were created by merging 20-cm radiocontinuum archival data, from the Australian Telescope Compact Array and the Parkes radio-telescope. Our images span from ~10'' to ~150'' in resolution and sensitivity of r.m.s.>=0.5 mJy/beam. These images will be used in future studies of the SMC's intrinsic sources and its overall extended structure.
