With the help of two new millimeter-wave telescopes, we should reveal answers to some of the most fundamental questions about the early Universe: Did inflation occur? How and when did the first structures form, and result in the ionization of the Universe? The Keck Array CMB polarimeter seeks to answer the first question by measuring the gravitational wave signature in the polarization of the CMB. The Keck Array relies on compact, high throughput telescopes to maximize sensitivity over large angular scales. I will discuss the experiment and give an overview of its design and a look forward to first results. The TIME imaging spectrometer will study large-scale structure at high redshifts and into the epoch of reionization. Our experiment aims to detect the aggregate emission of ionized carbon (158 micron) from the faint galaxies responsible for ionization using an emerging technique called intensity mapping. I will outline the key scientific questions we seek to answer, and the series of instruments we have started to build to explore the final cosmological frontier of the matter-dominated era.
