The information content of Cosmic Infrared Background anisotropies

Understand

We use analytic computations to predict the power spectrum as well as the bispectrum of Cosmic Infrared Background (CIB) anisotropies.

• Our approach is based on the halo model and takes into account the mean luminosity-mass relation.
• The model is used to forecast the possibility to simultaneously constrain cosmological, CIB and halo occupation distribution (HOD) parameters in the presence of foregrounds.
• For the analysis we use wavelengths in eight frequency channels between 200 and 900$\;\mathrm{GHz}$ with survey specifications given by Planck and LiteBird.
