SUMMARY:The Dark Matter at the End of the Galaxy
DESCRIPTION:Featuring Mariangela Lisanti\, Princeton University\n\nPart of 
	the HET Seminar Series.\n\nAbstract:\nDark matter density profiles based up
	on Lambda-CDM cosmology motivate an ansatz velocity distribution function w
	ith fewer high velocity particles than the Maxwell-Boltzmann distribution o
	r proposed variants. The high velocity tail of the distribution is determin
	ed by the outer slope of the dark matter halo\, the large radius behavior o
	f the Galactic dark matter density. N-body simulations of Galactic halos re
	produce the high velocity behavior of this ansatz. Predictions for direct d
	etection rates are dramatically affected for models where the threshold sca
	ttering velocity is within 30% of the escape velocity.
