CHIME collaboration helps identify location of "missing" matter in the universe

Estimates of ordinary matter in the universe exceed the amount observed in stars and galaxies, leaving much of it unaccounted for. Researchers from the Canadian Hydrogen Intensity Mapping Experiment (CHIME)/Fast Radio Bursts Collaboration, including ɬ�﷬ and MIT, have developed a new method to seek out this “missing” matter by combining galaxy locations with fast radio burst detections. A fast radio burst, or FRB, is an ultrabright, millisecond flash of radio waves emitted by extremely energetic phenomena in the distant universe.

How different were galaxies in the early universe?

An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting the “cosmic dawn” — the era after the Big Bang when stars first ignited and galaxies began to bloom.

A team of scientists from across North America, Europe, and South Africa has doubled the sensitivity of a radio telescope called the Hydrogen Epoch of Reionization Array (HERA). With this breakthrough, they hope to peer into the secrets of the early universe.
