We use the CN/CO intensity ratio to obtain the dense gas fraction. f _dense . for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties. We find a significant correlation between f _dense and star formation rate calculated using both IR luminosities and radio continuum. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC550-WUH721816ALE6L0-0F38460-16TB-7-2K-RPM-SATA-6Gb-s-512e-ISE-3-5in-Hard-Drive/
