The Canadian Hydrogen Intensity Mapping Experiment
CHIME is a new radio telescope, funded by the Canada Foundation for Innovation, being built in Penticton, British Columbia. CHIME will map the distribution of matter in the universe as traced by neutral hydrogen gas. This three-dimensional map will enable cosmologists to better discern the cause of the Universe's accelerating expansion.
CHIME will observe over half the sky and measure a redshift range from 0.8 to 2.5. This data will be used to produce a map of cosmic structure over the largest volume of the universe ever observed, with enough spatial resolution to discern the "baryon acoustic oscillations" that were imprinted on cosmic structure at early times.
CHIME is a partnership between the University of British Columbia, McGill University, and the University of Toronto and will be hosted at the DRAO.
