Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation

Understand

We present new measurements of CIB anisotropies using Planck.

• Combining HFI data with IRAS, the angular auto- and cross frequency power spectrum is measured from 143 to 3000 GHz, and the auto-bispectrum from 217 to 545 GHz.
• The total areas used to compute the CIB power spectrum and bispectrum are about 2240 and 4400 deg^2, respectively.
• After careful removal of the contaminants, and a complete study of systematics, the CIB power spectrum and bispectrum are measured with unprecedented signal to noise ratio from angular multipoles ell~150 to 2500, and ell~130 to 1100, respectively.
