Abstract

I\'ll discuss three promising upcoming experimental measurements that will probe the expansion history of the universe: (1) growth bases tests of Dark Energy with the Sunyaev-Zeldovich Effect, including new results from the South Pole Telescope and APEX-SZ, (2) inflationary constraints that will be provided by the next generation of CMB-polarization experiments, with prospects from EBEX, and (3) standard ruler measurements from Baryon Acoustic oscillations, including an introduction to an ambitious new Canadian Hydrogen Intensity Mapping initiative called CHIME. The talk will build on the PI-presentation last week from SPT-collaborator Jeff McMahon. I\'ll focus on the experimental aspects of each measurement, it\'s interface to theory, and spend most of the time on (3) CHIME.
