Star formation rate-stellar mass diagram of galaxies detected in the MUDF. The gray density contours show the distribution of all galaxies selected with HST in the rest-frame optical/UV at z∼1−2. The marginalized distributions of M_★ and SFR are also shown on the top and right axis, respectively. The red density contours report the sample of SMG with photometric redshift within 1≤z≤2.5 from Dudzevičiūtė et al. (2020). The ALMA-selected galaxies with properties derived from SED modeling are reported with diamonds. Colored triangles mark the HST-selected group galaxies associated with the same absorption system of each ALMA-selected galaxy. The star-forming main sequence at z∼1−2 from Popesso et al. (2023) is also shown.
