Below are astronomical images taken by myself and my collaborators
of astronomical objects or of simulations. You are free to download
them for yourself, as long as: 1) They are not used for profit, and
2) you credit us. A link back to our homepages would be nice also ....
The images shown are postage stamps of the larger images. Click on the
image, if you'd like to see the larger version.

Fornax Cluster
An artist's conception of an intracluster planetary nebulae, viewed
from a hypothetical planet. An image of the
Virgo Cluster lies in the background. This figure was done by
my friend Anna Jangren.
Some pretty images of simulated galaxy clusters, taken from the work of Dubinski (1998). The left column shows a galaxy cluster at Z=2, where the cluster is just forming, and the right column shows now (Z=0). The top row shows the N-body particles. The middle row shows the image smoothed by our adaptive kernel, to make a smooth picture. Intracluster light is clearly visible on many spatial scales. Finally, the bottom row shows what happens when you "observe" the data, using the same parameters that we observe on. A lot of features disappear into the noise, but some are still visible.
Nearby Planetary Nebulae:
SBS 1150+599A - The most metal-poor planetary nebulae yet discovered.
This is an H-alpha image with the central star subtracted, so that
you can see the nebula alone. It looks strangely
square, with some enhanced emission across the center
