Abstract
(abridged) HCN luminosity Lhcn is a tracer of DENSE molecular gas, n(H_2) >~ 3x10^4 cm^{-3}, associated with star-forming giant molecular cloud (GMC) cores. We present the results and analysis of our survey of HCN emission from 65 infrared galaxies including 9 ultraluminous infrared galaxies (ULIGs, Lir>10^{12}Lsun), 22 luminous infrared galaxies (LIGs, 10^{11}
