Comparison of CO(1–0) and [C I(1–0)] sizes with [C II], ALMA 870 μm continuum, and JWST 4.4 μm continuum.
| Tracer | R1/2 [kpc] | Reference |
|---|---|---|
| CO(1–0) | 3.8 ± 0.5 | This work |
| [C I](1–0) | ≤2.6 | This work |
| 870 μm | 1.1 ± 0.3 | Gullberg et al. (2019) |
| 870 μm | 1.8 ± 0.1 | Hodge et al. (2016) |
| 4.4 μm | 2.7 ± 0.2 | Gillman et al. (2024) |
| 4.4 μm | 3.0 ± 0.3 | Hodge et al. (2025) |
Notes. We list the 870 μm and 4.4 μm sizes for the AS2UDS and AS2COSMOS surveys (Gullberg et al. 2019; Gillman et al. 2024) (the parent samples of the AS2VLA survey) and the ALESS survey (Hodge et al. 2016, 2025).
