CIBxLIM

Code for computing the Cosmic Infrared Background Powerspectrum coupled with Line Intensity signal.

Dependencies

• Colossus (Halo mass function and Halo Bias) https://bdiemer.bitbucket.io/colossus/index.html
• halomod (Alternative HMF & Halo Bias) https://github.com/halomod/hmf

Models

• Under LinearModel, the linear, non halo mass dependent model for the CIB emissitivity. Accurate at large scales for the 2-halo terms, conveniently where the CIB signal dominates over the Line Intensity signal. Derivations and fitted parameter found in Maniyar 2018.
• Under HaloModel, the Halo Mass corrected model accuate to small scales within the one halo term according to Maniyar 2020. Also incorporates the subhalo mass function according to Tinker 2018

Data files

• SED.fits, redshift dependent Spectral Energy Distribution for the luminous star forming galaxy accross the Planck survey frequencies [100, 143, 217, 353, 545, 867, 3000] GHz
