Fast Radio Bursts

Fast Radio Bursts (FRBs) are brief, intense flashes of radio frequency emissions from distant celestial sources. They typically last only a few milliseconds and can emit as much energy in that short time as the Sun does in an entire day. Discovered in 2007, FRBs are characterized by their high brightness and the rapid variability of their signals. While their exact origins remain largely mysterious, they are thought to be associated with high-energy astrophysical processes, potentially linked to neutron stars, supernovae, or even unknown phenomena in the universe. The study of FRBs is significant in astrophysics, as they can provide insights into the intergalactic medium and the expansion of the universe.
