Zusammenfassung
The cosmic infrared background (CIB) is a powerful probe of large-scale
structure across a very large redshift range, consisting of unresolved
redshifted infrared emission from dusty galaxies. It can be used to study the
astrophysics of galaxies, the star formation history of the Universe, and the
connection between dark and luminous matter. It can furthermore be used as a
tracer of the large-scale structure and thus assist in delensing of the cosmic
microwave background (CMB). The major difficulty in its use lies in obtaining
accurate and unbiased large-scale CIB images that are cleaned from the
contamination by Galactic dust. We used data of neutral atomic hydrogen from
the recently-released HI4PI Survey to create template maps of Galactic dust,
allowing us to remove this component from the Planck intensity maps from 353 to
857 GHz for approximately $25\%$ of the sky. This allows us to constrain the
CIB power spectrum down to $\ell70$. We present these CIB maps and the
various processing and validation steps that we have performed to ensure the
quality of these maps, as well as a comparison with previous studies. All our
data products are made publicly available at http://bit.ly/PlanckCIB, thereby
enabling the community to investigate a wide range of questions, related to the
Universe's large-scale structure.
