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.pomyslnaszycie.com/vegetable-glycerin-sale/
