Context
Canadian Hydrogen Intensity Mapping Experiment (CHIME) have assembled the largest collection of fast radio bursts (FRBs).
- Researchers at the Pune-based Tata Institute for Fundamental Research (TIFR) and the National Centre for Radio Astrophysics (NCRA) achieved it.
About
About CHIME
- Stationary: It is a novel radio telescope that has no moving parts.
- It is located in British Columbia, Canada.
- First exploration: The telescope has detected more than 500 new fast radio bursts in its first year of operation itself, between 2018 and 2019.
- Tasks: It was originally conceived to map the most abundant element in the universe, that is Hydrogen.
- CHIME has also discovered new "Fast Radio Bursts" and for monitoring many pulsars on a daily basis.
- Working: This telescope is optimized to have a high "mapping speed", which requires a large instantaneous field of view (~200 square degrees) and broad frequency coverage (400-800 MHz).
- The digitized signals collected by CHIME will be processed to form a 3-dimensional map of hydrogen density, which will be used to measure the expansion history of the universe.
