21cm Intensity Mapping

By: Kevin Bandura (McGill University)

Dark Energy is arguably the greatest mystery in science today.  A promising technique in the pursuit of unraveling the mystery of Dark Energy is 21cm intensity mapping observations. I will discuss observational and instrumentation advances to date.  In particular I will introduce the Canadian Hydrogen Intensity Mapping Experiment (CHIME currently under construction at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, BC. I will detail the novel telescope design concept, details about the correlator, and the current commissioning of the 1/10th scale CHIME pathfinder.

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
