In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs – how long they last, the frequencies of the radio waves detected, and so on.</p> Wed, 14 Apr 2021 18:00:37 +0000 katherine.gombay@mcgill.ca 259829 at /newsroom /newsroom/channels/news/discovery-fast-radio-burst-pulses-regular-intervals-322835 <p>A Canadian-led team of astronomers, including researchers from ƽÌØÎå²»ÖÐ, has discovered that a repeating fast radio burst (FRB) originating from a nearby galaxy pulses at regular intervals.</p> <p>Researchers within the <a href="https://chime-experiment.ca/">Canadian Hydrogen Intensity Mapping Experiment</a> (CHIME) Fast Radio Burst Collaboration used the CHIME telescope in British Columbia to show that the repeating radio source known as FRB 180916.J0158+65 – first discovered in 2018 by the same group - pulsates apparently every 16.35 days.</p> Wed, 17 Jun 2020 20:03:22 +0000 justin.dupuis@mcgill.ca 217081 at /newsroom
