PYCAMB with time-varying DE EoS

Post by Williams Ribeiro » September 26 2018

Dear all,

I want to run pycamb with a time-varying dark energy equation of state. In CAMB, we just need to use equations_ppf.f90 instead of equations.f90, but I can't find an analogous in CAMB python wrapper. Does pycamb have support for ppf? If not, is it possible to do it somehow? Thanks for the help!

Yes, but you need to use the devel branch from github. (it supports a general w(z) as well as w0,wa, and you can dynamically switch between PPF and fluid dark energy models). Note that if compiling with gfortran you need version 6 or higher.
