The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities

Steven Gillman, Kei Ito, Francesco Valentino +25

We present a detailed study of near-infrared (2-4$\mu$m) JWST/NIRSpec spectra of 48 high-redshift ($z=2.53_{-0.70}^{+1.32}$) galaxies detected with ALMA at $>3\sigma$. From a multi-wa…
