Same region as above. Blue particles represent dark matter, red particles represent gas, and yellow particles represent gas that has been partially or completely converted into collisionless stars. A zoomed view of a region in the upper left corner of the large scale view. Zoomed view of the central object from the above region. Blue particles represent dark matter, red particles represent gas, and yellow particles represent gas that has been partially or completely converted into collisionless stars.
Vectors indicate the direction and magnitude of the particle velocities.
However, the whole system is not much larger than the gravitational softening length of the simulation, so the details of its internal structure should not be trusted. Note that much of the gas has settled into a relatively thin disk, though the outer gas has a different axis of rotation from the inner gas. The green clumps thus indicate the locations of the high-redshift galaxies.
