Episode 4. Repeating Fast Radio Bursts with Dr. Shami Chatterjee

Dr. Shami Chatterjee explains the significance of his discovery of repeating fast radio bursts!
In a galaxy far, far, away......
When multiple radio bursts come from the same source, or location in our sky, we interpret it to be something more substantial than a single explosive event. After hours of failing to observe a repeated signal and accumulating dozens of terabytes of data of video recordings of the night sky, the team finally had a breakthrough! A third observation attempt locked in the source of the radio bursts! 2.5 to 3 billion light years away, far outside the reach of our own galaxy and cosmic neighborhood, a dwarf galaxy is the possible culprit. The extreme distance means the energy emission producing these radio bursts has to be immense but, the source of the energy is yet to be determined!

Here is a summary of the paper that was released this year in Nature: https://arstechnica.com/science/2017/01/researchers-pin-down-the-location-of-a-mysterious-fast-radio-burst/
