A new study shows how scientists discovered a record-breaking radio signal from an extremely distant galaxy.
Scientists have detected a record-breaking radio signal from atomic hydrogen in a very distant galaxy. The galaxy that the signal originated from is believed to have come from a galaxy at redshift z=1.29. Because of the galaxy’s immense distance, the emission line had shifted to a 48 cm line from the 21 cm line they had expected.
This discovery is phenomenal because the galaxy that it originated from is believed to have existed when the universe was only 4.9 billion years old – making the source of the record-breaking radio signal 8.8 billion years old.to detect and follow the signal back to its source galaxy. The magnification of the lensing was a factor of 30, the scientists explained, which allowed the group to see through the high redshift of the universe.
M74 shines at its brightest in this combined optical/mid-infrared image, featuring data from both the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope. Image source: ESA/Webb, NASA & CSA, J. Lee and the PHANGS-JWST Team; ESA/Hubble & NASA, R. Chandar Acknowledgement: J. Schmidt, and they show that the overall feasibility of observing the atomic gas in galaxies at long distances.
The astronomers involved in the study work with the McGill University in Canada, as well as the Institute of Science in Bengaluru. The team used data from the Giant Meterwave Radio Telescope in Pune. This instrument allowed the team to detect the record-breaking radio signal originating from the distant galaxy, allowing the researchers to dig deeper into the discovery.
By detecting these kinds of record-breaking radio signals, we may be able to use similar instances to explore the
