Physical Society ColloquiumInterview for Faculty PositionThe Cosmic Microwave Background at High ResolutionGilbert HolderPrincetonThe cosmic microwave background (CMB) has been a gold mine for cosmology, but up to now most studies have been at relatively coarse resolution (tens of arcminutes). At higher resolution (a few arcminutes or better) a wealth of information is imprinted in the CMB from structures that have formed relatively recently. These imprints are primarily from Compton scattering (the Sunyaev-Zel'dovich effect) and gravitational lensing. I will review recent work in high-resolution studies of the CMB and explain the prospects for near-future (a few months to a few years) experiments to precisely measure cosmological parameters, study the process of structure formation in the universe, and better understand the properties of dark energy.
