Blake Sherwin, UC Berkeley, "CMB Lensing: Fundamental Physics from Maps of the Invisible"
Astronomy seminar: Dec 5 @ 12PM, ERC 401
Dark matter not only forms an invisible cosmic scaffolding within which galaxies form, its distribution in the universe also contains a wealth of information about neutrinos, inflation, and dark energy. Measurements of gravitational lensing in the cosmic microwave background (CMB) allow this matter distribution to be directly seen and mapped out to high redshifts.
