COSMOS2020-MIPS-PACS-SPIRE-SCUBA catalog

To speed up flux prediction, we made use of a neural network-based emulator. After deblending the 24um data, we proceeded to the Herschel PACS (100 & 160um) and SPIRE wavebands (250, 350 & 500um). Each time we constructed a tailor-made prior list based on the predicted fluxes of the known sources, taking into account the deblended photometry from the previous steps.

Using simulated far-IR and sub-mm sky, we detailed the performance of our deblending pipeline. After validation with simulations, we then deblended the real observations from 24 to 500um and compared with blindly extracted catalogues and previous versions of deblended catalogues. As an additional test, we deblended the SCUBA-2 850um map and compared our deblended fluxes with ALMA measurements, demonstrating a higher level of flux accuracy compared to previous results.

We publicly release our XID+ deblended point source catalogues, including best estimates and posterior probability distribution functions. These deblended long-wavelength data, which are cross-matched with multi-band photometry by construction, are crucial for studies such as deriving the fraction of dust-obscured star formation and better separation of quiescent galaxies from dusty star-forming galaxies.
