Abstract
Dusty star-forming galaxies emit a lot of photons in the infrared wavelengths that form the Cosmic Infrared Background (CIB). The CIB map, therefore, indicates the large-scale distribution of young blue galaxies as it is galactic dust that determines how the map forms. Cosmic Microwave Background (CMB) is the most ancient light in our Universe, with these photons travelling all the way from the last opaque surface of the big bang up to our telescopes. These photons, on their way, interact with matter along the direction of observation, via both gravitational and electromagnetic forces. By cross-correlating the CIB and CMB maps, we can extract a wealth of tomographic information on star formation history, growth of structure, etc. To analyze these maps, we look at their respective Temperature Power Spectrums, graphs showing the amount of radiation collected in various angular spans of the sky.
