Comet and Meteorite Traditions of Aboriginal Australians
Of the hundreds of distinct Aboriginal cultures of Australia, many have oral
traditions rich in descriptions and explanations of comets, meteors,
meteorites, airbursts, impact events, and impact craters. These views generally
attribute these phenomena to spirits, death, and bad omens. There are also many
traditions that describe the formation of meteorite craters as well as impact
events that are not known to Western science.Comment: Encyclopaedia of the History of Science, Technology, and Medicine in

The dimension of affine Deligne-Lusztig varieties in the affine Grassmannian of unramified groups
In this paper we calculate the dimension of affine Deligne-Lusztig varieties
in the affine Grassmannian of unramified groups. We also examine the
irreducible components of ADLVs in the superbasic case and the -action
on them.Comment: 24 pages, v2: Corrected typos and added details in the calculation
