This repository contains lensing power spectrum computations from the following paper:
Chung, Foreman, and van Engelen, Baryonic effects on CMB lensing and neutrino mass constraints, Phys. Rev. D 101, 063534 (2020), arXiv:1910.09565
These computations are made using matter power spectra measured from the OWLS, IllustrisTNG, Horizon, and BAHAMAS simulation suites. Please refer to the paper for more details.
The first column contains ell values the spectra were evaluated at, and each remaining column is the ratio of two computations of the CMB lensing power spectrum: the numerator uses the matter power spectrum from a certain hydrodynamical simulation, and the denominator is the lensing power spectrum in the absence of any baryonic effects (i.e. what would be generated by a pure N-body simulation, only incorporating the effects of gravity). These computations are shown in the colored curves in Fig. 1 of Chung et al. 2019.
- October 2020: update to fix error in computations. Updated spectra used for erratum to published paper and arXiv v3
- October 2019: version used in published paper and arXiv v1, v2
