Homogeneous Cosmology animations

• Author: Florent Leclercq
• Last update: 27/07/2023

This repository contains some python scripts producing plots and animations to explain homogeneous cosmology within different models (standard cold dark matter, Lambda cold dark matter, and dynamic dark energy). They are meant mostly for outreach purposes.

This material has been originally used in my talk at the 33ème Festival d'Astronomie de Fleurance (2023) : "Le satellite Euclid et l'analyse de ses données : énergie noire, information et incertitudes".

Captions and labels are intentionally not included in the plots/animations.

Installation

This is standard, low-weight python, written with python 3. Main dependencies are the following (to be installed by the user):

• numpy
• scipy
• astropy
• matplotlib
• widgetsnbextension

Outputs

Plots and animations are located in the output directory.

Using and contributing

You can use all of these products freely, but giving credit (for instance by citing the address of this repository and/or my talk at the 33ème Festival d'Astronomie de Fleurance) would be appreciated.
