- W4290744430 abstract "Dusty star-forming galaxies (DSFGs) at redshift z$geq$1 are among the most vigorously star-forming galaxies in the Universe. However, their dense ($geq$10$^5$ cm$^{-3}$ ) gas phase - typically traced by HCN(1-0) - remains almost entirely unexplored: only two DSFGs have been detected in HCN(1-0) to date. We present results of a JVLA survey of the J=1-0 transition of HCN, HCO+, and HNC(1-0) in six strongly lensed DSFGs at z = 2.5 - 3.3, effectively doubling the number of DSFGs with deep observations of these lines. We detect HCN(1-0) emission in one source (J1202+5354, 4.4$sigma$), with a tentative HCO+ (1-0) detection in another (J1609+6045, 3.3$sigma$). Spectral stacking yields strict upper limits on the HCN/FIR ($leq$3.6$times$10$^{-4}$) and HCN/CO(1-0) ratios ($leq$0.045). The inferred HCN/FIR ratios (a proxy for the star-formation efficiency) are consistent with those in z$sim$0 FIR-luminous starbursts. However, the HCN/CO ratios - a proxy for the dense-gas fraction - are a factor of a few lower than suggested by the two previous DSFG detections. Our results imply that most DSFGs have low dense-gas fractions. A comparison with Krumholz & Thompson (2007) models of star-forming galaxies indicates that the bulk of gas in DSFGs is at lower densities ($approx$10$^2$ cm$^{-3}$ ), similar to normal star-forming galaxies, rather than ultraluminous starbursts." @default.
