Much ado about nothing

Ravi Sheth (U Pittsburgh ) - November 17 (Monday) at 12:00 noon

Galaxy surveys show the presence of large voids (characteristic radii about twenty megaparsecs). It is sometimes argued that the voids in the galaxy distribution are much too large to be easily accomodated in CDM models. To address this, I'll discuss a simple model of voids in the dark matter distribution, and what the model implies for the properties of void galaxies.

The seminar will be held in 501 Campbell Hall.
