Computing the X-Ray Universe Movie: text

What are X-ray clusters?

X-ray telescopes orbiting the Earth have discovered that clusters of galaxies are immersed in halos of million degree gas. This hot gas is a byproduct of the galaxy formation process and emits large amounts of energy in the form of X-rays.

So luminous are these X-ray clusters they are visible to cosmological distances. Consequently, astronomers study X-ray clusters because they map out the large scale structure of the universe. Here, we study the formation of X-ray clusters by means of numerical simulations.
