_*JEFFERSON LAB COLLOQUIUM*_

*The Cosmic Microwave Background:*
*Beyond the Power Spectrum*


*Marc Kamionkowski*

*Dept. of Physics & Astronomy*

*ABSTRACT*
Virtually all the information we've obtained from the cosmic microwave 
background (CMB) about cosmological parameters and the early Universe 
comes from measurements of the temperature power spectrum or, 
equivalently, the temperature two-point correlation function. However, a 
variety of higher-order correlations, and the polarization, may encode a 
wealth of additional information on the early Universe, the physics of 
cosmic acceleration, and the distribution of matter at low redshifts. 
The guest speaker will discuss some of these new signatures as well as 
the physical scenarios.

*Wednesday, Nov. 16, 2011*
*4 p.m.*
*CEBAF Center auditorium*
*Cookies & coffee in the CEBAF Center lobby, 3:30 p.m.*
