A simulation of an "extensive air shower" striking the Milagro detector at
Los Alamos National Lab -- electrons and photons strike the top of the
atmosphere, creating a pancake of secondary particles that move very nearly
at the speed of light. Shown are electrons (red) and a few gamma rays (green).
When the electrons strike the Milagro detector pond, they emit copious
numbers of Cerenkov photons, shown in blue. Available are a
still picture (72 kb) and a
Quicktime movie (12 Mb). Simulation and
visualization by Miguel Morales, Santa Cruz Institute for Particle Physics.
Many more movies are available at the
Milagro
animation web site.

Subsonic flow over a
delta wing (300 kB)
aircraft with a vortex-shedding problem,
possibly leading to vibration. Colors represent 3D velocity magnitude and
texture represents direction. Simulation by NASA Ames Research Center.

A demonstration of direct volume rendering on a
multiply-gridded space shuttle launch vehicle
(2.5 Mb)
during the supersonic phase of its launch. Colors represent
air pressure, with red highest. Several shocks are clearly visible.
Simulation by Buning et al., NASA Ames Research Center. Visualization by
Wilhelms, Van Gelder and their students, UCSC Computer Science Dept.

Regions of high (red) and low (blue) irradiance for a
laser beam
propagating through a region of strong turbulence in the atmosphere.
This particular simulation is appropriate for propagation
at high altitude over distances of a few kilometers. The picture
is about one meter on a side. Simulations and visualization by
Flatté and Gerber, UCSC Physics Dept.

An N-body simulation of
large-scale structure in the universe.
Dark matter
"halos" (regions that are gravitationally bound) are shown color-coded by their
mass. The stars represent recent halo mergers, believed to lead to energetic
but short-lived star formation when the universe was young. Note how
the stars are clustered around the largest halos, a property shared by
observed very distant galaxies. Simulation by Kravtsov, Klypin & Kokhlov
New Mexico State University and US Naval Research Lab. Visualization by
Johnsson, UCSC Astronomy & Astrophysics Dept.

Telescope data, from a "drift scan" of a section of the Large Magellanic
Cloud. The animation was made using IDL by Dennis Zaritsky, UCSC
Astronomy & Astrophysics Dept. Available for download are a
large animation (6 Mb; very spiffy) or a
smaller version of the same thing (0.7 Mb).
