CHIME - the Canadian Hydrogen Intensity Mapping Experiment - Livestream

> The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is an ambitious project to study Dark Energy by tracing out 4 billion years of cosmic history, using a purpose-built radio telescope at the Dominion Radio Astrophysical Observatory (DRAO) in B.C.’s Okanagan Valley. Subsequent extensions simultaneously probe the high-cadence time-domain radio sky, monitoring radio pulsars and detecting hundreds of Fast Radio Bursts (FRBs).

CHIME is a transit interferometer with no moving parts, which uses a massive computing backend to image the radio sky from 400-800MHz, corresponding to 21cm radiation emanating from a redshift range of 0.8 < z < 2.5. Earth rotation sweeps its field of view across the sky, resulting in complete daily coverage of the northern celestial hemisphere and an unprecedented survey sensitivity. I will discuss the motivation, construction, status of CHIME, along with some recent results. Looking forward, I will present the technology path towards adding FRB localization capabilities to CHIME, and the new wide-band CHORD telescope, presently under development in Canada.
