Speaker
Description
In this talk, I introduce a semi-analytic model designed to evaluate the Cosmic Infrared Background (CIB) power spectrum across all frequency and multipole ranges. Our methodology starts from the Halo Model, in order to describe the dark matter distribution in the Universe, capturing its non-linear behavior. We further extend the Halo Model formalism to galaxies, populating dark matter halos with two distinct galaxy populations that exhibit different clustering behaviors and emissivity functions. Via MCMC analyses over Planck and SPIRE data, we constrain the clustering parameters. Our findings indicate discrepancies across different frequency and multipole ranges, either hinting to limitations of the model or suggesting a tension among the experiments.
