Building on the archives: Connecting the CN/CO intensity ratio with global galaxy properties in nearby U/LIRGs
Blake Ledger, Christine D. Wilson, Osvald Klimi +2
We use the CN/CO intensity ratio to obtain the dense gas fraction, , for a sample of 16 Ultra-luminous and Luminous Infrared Galaxies and compare $f_{\text{dense}…
