Fast Radio Bursts

Fast Radio Bursts (FRBs) are brief, intense flashes of radio frequency emissions from distant galaxies, lasting only milliseconds. First discovered in 2007, these cosmic signals are characterized by their sudden appearance and relatively large energy output, often comparable to the entire energy emitted by the Sun in a day compressed into a fraction of a second. The exact origins of FRBs remain largely mysterious, although they are thought to be associated with exotic astrophysical phenomena, such as neutron stars or their collisions, black holes, or other high-energy processes in the universe. FRBs can exhibit a wide range of frequencies and often display repeating signals, leading to various hypotheses about their sources and mechanisms. Their study provides valuable insights into the universe's structure, as their dispersion can reveal information about the intergalactic medium and the distribution of matter in the cosmos.
