The impact of clustering and angular resolution on far-infrared and millimeter continuum observations

Abstract

Follow-up observations at high-angular resolution of submillimeter galaxies showed that the single-dish sources are comprised of a blend of several galaxies. Consequently, number counts derived from low and high angular resolution observations are in disagreement. This demonstrates the importance of resolution effects and the need to have realistic simulations to explore them. We built a new 2deg^2 simulation of the extragalactic sky from the far-infrared to the submillimeter. It is based on an updated version of the two star-formation mode galaxy evolution model. Using global galaxy properties, we use the abundance matching technique to populate a dark-matter lightcone and thus simulate the clustering. We produce maps and extract the sources, and show that the limited angular resolution of single-dish instruments have a strong impact on (sub)millimeter continuum observations. Taking into account these resolution effects, we are reproducing a large set of observables, including number counts, redshift distributions, and cosmic infrared background power spectra. Our simulation describes consistently the number counts from single-dish telescopes and interferometers. In particular, at 350 and 500 um, we find that number counts measured by Herschel between 5 and 50 mJy are biased towards high values by a factor 2, and that redshift distributions are biased towards low z. We also show that the clustering has an important impact on the Herschel pixel histogram used to derive number counts from P(D) analysis. Finally, we demonstrate that the large number density of red Herschel sources found in observations but not in models could be an observational artifact caused by the combination of noise, resolution effects, and the steepness of color and flux density distributions.
