New 20-CM Radio-Continuum Study of The Small Magellanic Cloud: Part II - Point Sources Catalogue

TL;DR

This paper presents a comprehensive catalogue of radio-continuum sources in the Small Magellanic Cloud across three frequencies, enhancing previous surveys with new detections and high-resolution imaging.

Contribution

It provides the first detailed catalogue of radio sources in the SMC at 13 cm, 20 cm, and 36 cm, including new detections from high-sensitivity observations.

Findings

45 sources detected at 13 cm

1560 sources at 20 cm from new images

1689 sources catalogued at 36 cm

Abstract

We present a new catalogue of radio-continuum sources in the field of the Small Magellanic Cloud (SMC). This catalogue contains sources previously not found in 2370 MHz ({\lambda}=13 cm) with sources found at 1400 MHz ({\lambda}=20 cm) and 843 MHz ({\lambda}=36 cm). 45 sources have been detected at 13 cm, with 1560 sources at 20 cm created from new high sensitivity and resolution radio-continuum images of the SMC at 20 cm from Paper I . We also created a 36 cm catalogue to which we listed 1689 radio-continuum sources.
