TL;DR

This paper presents an atlas of CO-line maps around 63 Galactic supernova remnants, revealing molecular shells and cavities to study SNR-ISM interactions using high-resolution FUGIN data.

Contribution

It provides the first comprehensive atlas of molecular shells and cavities around SNRs using high-resolution CO data, aiding in understanding their interactions with the interstellar medium.

Findings

Identification of molecular shells and cavities around several SNRs.

Kinematic distances of SNRs derived from CO-line velocities.

Enhanced understanding of SNR-ISM interactions.

Abstract

A morphological} search for molecular shells and cavities was performed around 63 Galactic supernova remnants (SNR) at $10^\circ \le l \le 50^\circ$, $|b|\le 1^\circ $using the FUGIN (FOREST Unbiased Galactic Imaging survey with the Nobeyama 45-m telescope) CO line data at high angular ($20''$) and velocity (1.3 km s$^{-1}$) resolutions. The results are presented as supplementary data for general purpose for investigations of the interaction between SNRs and interstellar matter in the form of an atlas of CO-line maps superposed on radio continuum maps at 20 cm along with a list of their kinematic distances determined from CO-line radial velocities.
