A small python script to illustrate the how cosmological parameters affect the CMB. The user can modify certain cosmological parameters and see their effect on a random realization of the CMB. The idea is based on the "Build a Universe!" application, https://wmap.gsfc.nasa.gov/resources/camb_tool/index.html, which can no longer be used after flash player has expired.
Requirements:
-
the python package of CAMB (https://arxiv.org/pdf/astro-ph/9911177.pdf), which can be found at https://camb.readthedocs.io/en/latest/ and http://camb.info.
-
the python package of Healpix (https://arxiv.org/pdf/astro-ph/0409513.pdf), which can be found at https://healpy.readthedocs.io/en/latest/ and https://healpix.sourceforge.io/.
I recommend to create a new python environment before installing camb and healpy with "pip install camb" and "pip install healpy", it may request specific versions of standard packages.
