arge scales.

The computer simulation (name: BHCosmo) was carried out on the Cray XT3 at the Pittsburgh Supercomputer Center
+
-
by Tiziana Di Matteo (CMU) and the visualization by Yu Feng and Rupert Croft on
+
-
facilities provided by the Moore foundation in the McWilliams Center for Cosmology at CMU.
+
-
The full
+
-
image is 600 million light years in width and the density of matter is being
+
-
shown on a false color scale, with the densest regions in yellow
+
-
and the least dense in red and black.
+
-
The very densest regions have formed stars, which are shown as white points.
+
-
Unlike images of the real Universe seen
+
-
through optical telecopes, in the simulated image it is possible to see the film
+
-
entary structures that
+
-
stretch through the space between galaxies. These structures contain mostly hydrogen
+
-
and helium gas. The only luminous matter is in galaxies, which are much sparser.
+
-
To see these, we
+
-
zoom in, where small blobs of gas (in dark blue) and stars (in white) become apparent: t
+
-
hese are whole galaxies.
+
-
As the universe evolves from early times (it starts at an age of two hundred mil
+
-
lion years after the Big Bang)
+
-
the initially small fluctuations grow through the action of gravity until in the
+
-
last frame (which
+
-
represents the universe 7 billion years later, at redshift z=1) there are large
+
-
clusters of galaxies. If you zoom in and scroll around you will see that clusters contain
+
-
many small galaxies as well as large ones.
