In a statement released by University of Toronto, Lamiya Mowla, the lead author on the paper, said that since the launch of the Hubble Space Telescope more than 30 years ago, it has led a “renaissance in the study" of how galaxies have changed in the last 10 billion years of the universe. Named as 3D-DASH, the image contains many stars and several other celestial objects. As per researchers, it can help in understanding star-forming regions of the universe and extremely distant galaxies. Meanwhile, in another space discovery, NASA’s Hubble Telescope captured the largest near-infrared image ever. However, the researchers cautioned that some questions are still unanswered. The researchers have theorised that the FRB 190520 may be a “newborn," meaning, it is “still surrounded by dense material ejected by the supernova explosion that left behind the neutron star.” The theory states that once the material dissipates, the burst signals will also decline. “Now we actually need to explain this double mystery and why FRBs and persistent radio sources are found together sometimes,” she told CNN. However, big questions still remain, and this object is giving us challenging clues about those questions." Casey Law, of Caltech who is one of the co-authors of the study in a statement to the National Science Foundation said, “These characteristics make this one look a lot like the very first FRB whose position was determined - also by the VLA - back in 2016." The 2016 object is called FRB 121102 and the properties are similar to FRB20190520B. Sarah Burke-Spolaor, co-author of the study, in an official statement said, “The FRB field is moving very fast right now and new discoveries are coming out monthly. As per the researchers, the signal was “co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific-star-formation.” The discovery was made using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Guizhou, China, in May 2019.Īs per several observations, the emitting object was responsible for emitting smaller radio bursts between the FRBs. The researchers have detected a new Fast Radio Bursts (FRB), which has been termed FRB 20190520B. The findings have been published in the science journal Nature. Once earlier, such a repeating signal was detected by scientists.
However, this is not the first time that such a thing has happened.
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.īy detecting these kinds of record-breaking radio signals, we may be able to use similar instances to explore the mysteries of the early universe more thoroughly.In what comes as a strange discovery, astronomers have detected a radio signal coming from another galaxy, which happens to be nearly 3 billion light-years away from Earth. And swarms provide new opportunities, such as positioning multiple small spacecraft to function as one very large observatory, like a telescope with a huge field of view. The team used data from the Giant Meterwave Radio Telescope (GMRT) in Pune. The time it takes for communication signals to travel and constraints on data bandwidth make direct control of multiple deep-space satellites impractical. The astronomers involved in the study work with the McGill University in Canada, as well as the Institute of Science (IISc) in Bengaluru. It could also open new doors for probing the cosmic evolution of neutral gas with exiting and upcoming low-frequency radio telescopes in the future. These findings were published in the Monthly Notices of the Royal Astronomy Society, and they show that the overall feasibility of observing the atomic gas in galaxies at long distances. Lee and the PHANGS-JWST Team ESA/Hubble & NASA, R. 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. Further, the team observed that the atomic hydrogen mass of the galaxy was twice as high as its stellar mass. 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. The detection was possible because the scientists used gravitational lensing to detect and follow the signal back to its source galaxy.
