The Paris Local Universe Simulations: Dark Matter Sky Maps

This picture shows the result of a high resolution N-body simulation which has been specifically designed to look like the Local Universe.

#

Stability of a Primordial Gas Cloud

The first stars in the Universe formed out of primordial gas, which only consists of hydrogen and helium. We use hydrodynamical simulations to follow the collapse

#

Dancing in the Dark

The properties of the galaxies are shaped by the dynamics of the dark matter at large scale. On this picture coming from a cosmological simulation, each dot is a galaxy.

#

The Cosmic Microwave Background

The picture shows a map of the cosmic microwave background (CMB), that is the first visible light after the Big Bang, as recovered from the Planck satellite maps.

"This is the type of image we astronomers discard"

I came across this image whilst doing some work and it made me halt my work for a bit as I was taken by it’s beauty. What is seen is an extremely tiny part of the sky, ...

Sedov Taylor Blast Wave

In order to make sure that the used program is following the correct physics we often have to go back and simulate simple toy-models to which we already understand the solution.

A simulation of the Universe -- Horizon-AGN

Our Universe is far from being random. Billions of stars are organised into galaxies. Galaxies cluster together and align themselves along cosmic filaments.
