title: Data for Cosmic CO and [CII] Backgrounds and the Fueling of Star Formation over 12 Gyr

description: Data for Cosmic CO and [CII] Backgrounds and the Fueling of Star Formation over 12 Gyr

We provide empirical tomographic measurements of the cosmic CO and [CII] line backgrounds arising from the aggregate emission of galaxies and potentially diffuse gas in large-scale structure. Previously, only the most luminous galaxies were detected in these lines, revealing just the tip of the iceberg. Using the intensity mapping method, we measure the total background integrated over the entire line-emitting populations and report the cosmic mean. These measurements are based on detections of line excesses above the cosmic infrared background (CIB) continuum—at 7σ significance for CO and 3σ for [CII]—using CIB–galaxy correlations over 0 < z < 4.2, originally measured in Chiang et al. (2025, ApJ, 992, 1, 65). We use these redshift-dependent, multi-band correlation amplitudes to isolate the line contributions, which are released here.

The [CII] background corresponds to the 158 µm fine-structure line. The CO background includes the nine rotational transitions from J = 1–0 to 9–8, beginning at 115.27 GHz with equal spacing in frequency. Two sets of line posteriors are provided:

1. Comoving luminosity density   "rho_CO_CII--dense_z_fiducial.ecsv" gives the fiducial full-model posterior, sampled in dense    redshift bins over 0 < z < 10.   "rho_CO_CII--8_z_bins.ecsv" gives refits with independent line amplitudes in 8 redshift bins    within the range probed by the data (0 < z < 4.2), with all other nuisance parameters fixed to    their global best-fit values.    Both files are in units of L_sun/Mpc^3.

2. Monopole   "Tb_cosmic_CO_CII.ecsv" provides brightness temperatures in microkelvin (µK).   "I_nu_cosmic_CO_CII.ecsv" provides intensities in Jy/sr.   The two are equivalent. Both are derived from the full-model posterior, sampled densely over    0 < z < 10 and tabulated across observed frequency in GHz. Best-fit values correspond to    posterior medians, with lower and upper bounds indicating the 68% credible interval.

This data release serves as an empirical baseline for future line intensity mapping efforts and forecasts, and as a reference for comparison with galaxy surveys in astrophysical studies.
