Summary
Fast Radio Bursts (FRBs) are enigmatic pulses of radio waves that come from the distant Universe. In addition to the mystery of what produces them, FRBs can be used as a powerful tool to probe the missing ordinary matter in the Universe. This is the so-called "missing baryon problem", which has posed a challenge to astronomers for decades. The research team at Harvard University have a large data sample of FRBs thanks to the Deep Synoptic Array, an array of radio telescopes near Big Pine, California. They will use this sample to answer critical questions in the distribution of cosmic baryons.
