This artist’s impression (not to scale) illustrates the path of the fast radio burst FRB 20220610A, from the distant galaxy where it originated all the way to Earth, in one of the Milky Way’s spiral arms. The source galaxy of FRB 20220610A, pinned down thanks to ESO’s Very Large Telescope (VLT), appears to be located within a small group of interacting galaxies. It’s so far away its light took eight billion years to reach us, making FRB 20220610A the most distant fast radio burst found to date.
Fast radio bursts (FRBs) are bright flashes of radio waves that last only a few milliseconds and are visible across the universe. Although approximately 10,000 of these occur every day, they were only discovered by accident in 2007. Their origins remain largely unknown, making FRBs one of the hottest topics in radio astronomy. In this talk, Dr. McKee will describe the discovery of FRBs, what we know about them, and what the next few years of radio astronomy holds for this exciting new field of astronomy.

James McKee, Union College, Physics & Astronomy
Dr. McKee studied physics at the University of Hull, and obtained a PhD in astronomy and astrophysics at the University of Manchester while working at Jodrell Bank Observatory. Dr. McKee has held research positions at the Max Planck Institute for Radio Astronomy, where he was also the on-site pulsar astronomer at the Effelsberg radio telescope, and at the Canadian Institute for Theoretical Astrophysics at the University of Toronto where he worked on the CHIME telescope. He is currently an assistant professor of physics and astronomy at Union College in NY, where he leads research into pulsars and fast radio bursts.
