CAMB Python: Incorporating new cosmological model
Posted: May 23 2020
Instead of putting a new set of parameters, I would like to use a new cosmological model based on varying physical constants (e.g. arXiv 1705.03461, 1810.12090). I wonder if it would be possible to incorporate a new module to do so, or modify an existing function, module or subroutine. I understand currently I can only change the parameter of an existing ΛCDM model as below (same as in the online version of CAMB):
#Set up a new set of parameters for CAMB
pars = camb.CAMBparams()
#This function sets up CosmoMC-like settings, with one massive neutrino and helium set using BBN consistency
pars.set_cosmology(H0=67.5, ombh2=0.022, omch2=0.122, mnu=0.06, omk=0, tau=0.06)
pars.InitPower.set_params(As=2e-9, ns=0.965, r=0)
pars.set_for_lmax(2500, lens_potential_accuracy=0);
I am writing a research paper and any assistance would expedite completion and publication of this paper.
Thank you.
