We present a new extragalactic survey using ALMA to characterise galaxy populations at low-intermediate redshifts: the Valparaíso ALMA Line Emission Survey (VALES). We use ALMA Band-3 CO(1–0) observations to study the molecular gas content in a sample of 67 dusty normal star-forming galaxies selected from the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We detect 49 galaxies at 5 sigma significance with CO luminosities in the range of (0.03−4)x10^10 K km/s/pc^2. We examine the star formation efficiency in these systems, finding that most follow a long-standing mode of star formation with gas consumption timescales of 1-1.5 Gyr. For the 21 resolved galaxies, we provide a robust linear fit to the Schmidt-Kennicutt relation using disk-like galaxies. A significant number of galaxies at z~0.1 present high gas fractions that are similar to those measured in high-redshift systems. We identify a rapid increase of the gas content as a function of redshift. By comparing our CO(1-0) line observations and Herschel [CII] spectroscopy to the the predictions of a photodissociation region (PDR) model, we find that the neutral gas density also rapidly increases as a function of redshift, whereas the incident radiation field remains constant with redshift. Finally, we also study the correlation between the molecular gas content and the estimated dust continuum luminosity at 850 microns, obtaining a calibration in excellent agreement with previous literature values. In this talk, I will review the recent results from VALES, the status of our follow-up campaigns, and our search for local analogues of high-redshift galaxies.
