The second epoch Molonglo Galactic Plane Survey: images and candidate supernova remnants
A.J. Green, S.N. Reeves, and T. Murphy

TL;DR
The MGPS-2 survey provides high-resolution, sensitive images of the southern Galactic Plane, revealing new supernova remnant candidates and complex interstellar structures, contributing to understanding the Galaxy's SNR population.
Contribution
This paper presents the complete MGPS-2 survey images, including new SNR candidates and analysis of interstellar medium features, advancing Galactic Plane radio observations.
Findings
Identification of new SNR candidates
Detection of highly structured interstellar features
Discussion on the 'missing' SNR population
Abstract
The second epoch Molonglo Galactic Plane Survey (MGPS-2) covers the area bounded by 245deg < Galactic longitude < 365deg and Galactic latitude < |10|deg, at a frequency of 843 MHz and an angular resolution of 45" x 45" cosec(Dec.). The sensitivity varies between 1 - 2 mJy/beam depending on the presence of strong extended sources. This survey is currently the highest resolution and most sensitive large-scale continuum survey of the southern Galactic Plane. In this paper, we present the images of the complete survey, including postage stamps of some new supernova remnant (SNR) candidates and a discussion of the highly structured features detected in the interstellar medium. The intersection of these two types of features is discussed in the context of the "missing" SNR population in the Galaxy.
