The CCAT-prime project's first light array will be deployed in Mod-Cam, a single-module testbed and first light cryostat, on the Fred Young Submillimeter Telescope (FYST) in Chile's high Atacama desert in late 2022.

The simulation from the original Illustris project yields more SMGs than IllustrisTNG: the predicted counts are consistent with those observed at both $S_{850} \lesssim 5$ mJy and $S_{850} \gtrsim 9$ mJy and only a factor of $\sim 2$ lower than observed at intermediate flux densities.

We find its mass-to-light ratio is higher than galaxies of comparable stellar mass ($[M/L]_{\rm half} = 278^{+146}_{-198}M_\odot/L_\odot$), but its dynamics place it in a halo with a similar total mass to these galaxies.
