In news

  • Researchers from the Pune-based Tata Institute for Fundamental Research (TIFR) and the National Centre for Radio Astrophysics (NCRA), have assembled the largest collection of Fast Radio Bursts (FRBs) catalogue.
  • The data is from Canadian Hydrogen Intensity Mapping Experiment (CHIME).
  • In 2020, NASA spotted FRB for the first time in the Milky Way.
  • The new catalogue expands the current library of known FRBs, and is already helping in understanding their properties.

About Fast Radio Bursts (FRBs)

  • FRBs are bright bursts of radio waves whose durations lie in the millisecond-scale, because of which it is difficult to detect them and determine their position in the sky.
    • It was first discovered in 2007.
  • Their origins are unknown and their appearance is highly unpredictable.

About CHIME:

  • It is a novel radio telescope that has no moving parts. 
  • It is optimized to have a high mapping speed.
  • It is located at the Dominion Radio Astrophysical Observatory, Canada.

Significance of Studying FRBs

  • These phenomena can be used to answer some long-standing questions about the universe.
  • It can be used to understand the three–dimensional structure of matter in the universe
