abstract

We combine recent simulation work on the SFR--[C II] correlation at high redshift with empirical modeling of the galaxy--halo connection (via UniverseMachine) to forecast [C II] auto power spectra from $z\sim4$ to $z\sim8$. We compare these to sensitivities realistically expected from various instruments expected to come on-line in the next decade. If the predictions of our model are correct, [C II] should be detectable up to $z\sim6$ in this generation of surveys, but detecting [C II] past the end of reionization will require a generational leap in line-intensity survey capabilities.

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    The EoR-Spec Filter-and-Bin pipeline suppresses atmospheric 1/f noise by about four orders of magnitude and recovers the [CII]+CO power spectrum above k ~ 0.1 Mpc^-1, but suppresses large-scale modes below 20% transfe...

    astro-ph.GA 2026-07 conditional novelty 5.0 of 10

    Using a SAM-based mock, multi-line intensity-mapping cross-power spectra show dust acts as a line-pair- and redshift-dependent suppression, and PCA cleaning with about 20 modes best balances line recovery against cont...

  3. The CCAT-Prime Submillimeter Observatory

    astro-ph.IM 2019-09 unverdicted novelty 3.0 of 10

    A proposed submillimeter observatory, CCAT-prime, claims to deliver survey speeds an order of magnitude beyond current facilities for reionization and cluster studies.
