TL;DR
This study reports the first detections of high-J CS lines in M 82 and NGC 4038, revealing a denser, warmer molecular gas component associated with specific galactic features.
Contribution
It provides new observational data of high-J CS lines in two galaxies, highlighting the presence of a distinct, dense, and warm molecular gas component.
Findings
Detection of CS in NGC 4038 nucleus
First high-J CS line detections in M 82
Identification of a denser, warmer gas component
Abstract
We present the first detection of CS in the Antennae galaxies towards the NGC 4038 nucleus, as well as the first detections of two high-J (5-4 and 7-6) CS lines in the center of M 82. The CS(7-6) line in M 82 shows a profile that is surprisingly different to those of other low-J CS transitions we observed. This implies the presence of a separate, denser and warmer molecular gas component. The derived physical properties and the likely location of the CS(7-6) emission suggests an association with the supershell in the centre of M 82.
