CLASS vs CAMB: Comparative Analysis

This repository contains notebooks and scripts for comparing the outputs of CLASS (Cosmic Linear Anisotropy Solving System) and CAMB (Code for Anisotropies in the Microwave Background), the two most widely used Boltzmann codes in cosmology. The goal is to explore differences and similarities in their treatment of cosmological parameters, dark energy models, and resulting observables.

Overview

Purpose:
To provide clear, reproducible comparisons between CLASS and CAMB outputs for various cosmological scenarios, with a focus on dark energy and modified gravity models.
Approach:
Python-based wrappers and Jupyter Notebooks are used to run both codes, process their outputs, and visualize results side-by-side.

Features

Run CLASS and CAMB with identical cosmological parameters.
Generate and compare predictions for key observables (e.g., CMB power spectra, matter power spectra).
Explore effects of altering dark energy/modified gravity parameters.
Visualize differences with easy-to-edit plotting scripts.
Modular structure for adding new models and parameter scans.
