The ALPINE-CRISTAL-JWST Survey: Investigating the role of interstellar dust, gas and stars in high-z galaxies at kpc-scales
Year: 2026
Type: preprint
Abstract: A comprehensive understanding of galaxy evolution requires a detailed analysis of gas and dust, their distribution, and evolution within galaxies. We analyse spatially resolved (~kpc) rest-frame [CII] and dust continuum ALMA observations together with JWST/NIRSpec IFU data of a sample of galaxies at z~4-5. We focus on deriving the spatial distributions of atomic and molecular gas masses, dust and stellar masses, star formation rates (SFR), and metallicity. The oxygen abundance maps have values in the range of 12+log(O/H)~8.1-8.3 with variations of the order of 1dex within the same galaxy. The calibration used in this study to estimate the atomic gas mass in our galaxies seems to overestimate the atomic gas mass surface densities up to 1-2 orders of magnitude. However, a calibration based on a spatially resolved [CII] conversion factor gives a more robust estimation of the total gas mass. Galaxies exhibiting signatures of strong outflows have lower dust-to-stellar surface mass density ratio and lower gas mass fractions than the galaxies with no outflow signatures. While the latter is consistent with these galaxies ejecting part of their gas reservoir to the circumgalactic medium, the low dust-to-stellar surface mass density ratios also suggest that part of the dust content is expelled outside the galaxy, which reinforces previous theoretical suggestions of dust removal by stellar feedback or radiation pressure to explain the high UV luminosities in galaxies at very high-redshifts. Some galaxies of our sample have almost an order of magnitude higher dust-to-gas and dust-to-stellar surface mass density ratio than galaxies in the local Universe, suggesting that a large dust reservoir has been built up already at time scales of ~1 Gyr in these galaxies.
