Giant VHF Radio Telescope (GMRT) of India is one of the largest radio telescopes in the world, it received a unique signal from a region of space-time 8.8 billion years ago. This signal can help scientists better understand the birth and development of the universe.
It’s a atomic hydrogen signalA “the constituent elements of the universe” Particularly large phenomena, perhaps common in today’s world, are extremely rare and dangerous in remote areas of space, where distances of billions of light years mean that what we see are images from billions of years ago.
According to Scientific alert, A signal that exceeded all expectations was received by the Indian GMRT telescope, which, according to calculations, showed that it took 8.8 billion years to reach Earth.
How to use”“gravitational lenses” naturally by another galaxy that scientists used to obtain special signals – (Photo: Swadha Pardesi).
It is a 21 cm long light wave, extremely difficult to detect and far exceeds the previous record of 4.4 billion years.
To capture this incredible signal, a team of scientists led by cosmologist Arnab Chakaborty from McGill University (Canada) and astrophysicist Nirupam Roy from the Indian Institute of Science used the special observation method, in which another galaxy is used as a gravitational lens.
This lens “curves” space-time from the location containing the “cosmic building blocks” to Earth, In this case, it enlarges the signal by up to a factor of 30.
This helps their telescopes “time travel” literally billions of years, seeing things further than its true viewing range. It is determined that atomic hydrogen belongs to SDSSJ0826+5630a star-forming galaxy 8.8 billion years ago.
According to the research team, this discovery opens a new window on the early universe, on what contributed to the construction of the giant world of the universe to which we belong.
The study has just been published above Monthly Notices of the Royal Astronomical Society.
