Abstract:

The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a radio telescope that we built to map the large-scale structure of the Universe between redshifts $0.8<z<2.5$, when dark energy is expected to begin the transition from a decelerating to an accelerating phase in its expansion. It was designed to perform an intensity mapping survey using the 21 cm line of neutral hydrogen, a novel method that has the potential to enable enormous surveys of the distant Universe, but also significant observational challenges to overcome.
