Observed CN and HCN intensity ratios exhibit subtle variations in extreme galaxy environments
Abstract
ABSTRACT
We use both new and archival ALMA data of three energy lines each of CN and HCN to explore intensity ratios in dense gas in NGC 3256, NGC 7469, and IRAS 13120-5453. The HCN (3–2)/HCN (1–0) intensity ratio varies in NGC 3256 and NGC 7469, with superlinear trends of 1.53 ± 0.07 and 1.55 ± 0.05, respectively. We find an offset to higher HCN (3–2)/HCN (1–0) intensity ratios (∼0.8) in IRAS 13120-5453 compared to NGC 3256 …
