Abstract :
The CHIME (Canadian Hydrogen Intensity Mapping Experiment) instrument is a novel hybrid cylindrical interferometer designed to measure the large scale neutral hydrogen power spectrum across the redshift range from 0.8 to 2.5. The power spectrum will be used to measure the BAO (Baryon Acoustic Oscillation) scale evolution across this previously poorly probed redshift range across which dark energy begins dominating the content of the Universe.
