CMBEASY is a software package for calculating the evolution of density fluctuations in the universe. Most notably, the Cosmic Microwave Background temperature anisotropies.

CMBEASY is fast, accurate and comes with many useful features.

Here are some key features of "CMBEASY":

￭ Fully object oriented code
￭ Simple data handling using Spline objects
￭ Gauge invariant & synchronous gauge perturbations
￭ Arbitrary mixing of adiabatic or isocurvature initial conditions
￭ CDM Powerspectrum can be output at arbitrary time or wavenumber
￭ Full quintessence support:
￭ Arbitray equation of state class
￭ Inverse power law and exponential potential class
￭ Leaping kinetic term and crossover quintessence class
￭ Varying fine structure constant support
￭ AnalyzeThis class compares models to CMB, SNe Ia and LSS data
￭ Generic parallel Monte Carlo driver included
￭ Browsable auto generated online documentation
￭ Graphical user interface featuring ...
￭ A powerful plot-widget
￭ Printing and saving of curves
￭ Handling of 2-D and 1-D marginalized likelihoods from Monte Carlo
￭ Powerful printing engine for likelihood contours
￭ Axis label can be input in latex syntax (not 100% perfect but very useful)
￭ Two different methods to get the 2-D likelihood contours: easy to crosscheck for disconnected regions

Requirements:

￭ In order to build cmbeasy, you need to have cmake installed.
