Large-scale Maps of the Cosmic Infrared Background from Planck
  The cosmic infrared background (CIB) is a powerful probe of large-scale
structure across a very large redshift range, and consists 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 de-lensing of the cosmic
microwave background. The major difficulty in its use lies in obtaining
accurate and unbiased large-scale CIB images that are cleaned of the
contamination by Galactic dust. We used data on 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 $\ell\gtrsim 70$. We present these CIB maps and the
various processing and validation steps that we have performed to ensure their
quality, as well as a comparison with previous studies. All our data products
are made publicly available at https://doi.org/10.7910/DVN/8A1SR3, thereby
enabling the community to investigate a wide range of questions related to the
universe's large-scale structure.
