Excitation mechanisms for hcn(1-0) and hco+ (1-0) in galaxies from the great observatories all-sky lirg survey

Abstract

We present new Institut de Radioastronomie Millimetrique (TRAM) 30 m spectroscopic observations of the similar to 88 GHz band, including emission from the CCH (N = 1 -> 0) multiplet, HCN (J = 1 -> 0), HCO (J = 1 -> 0), and HNC (J = 1 -> 0), for a sample o
