The FAST telescope was in charge of detecting signals in China
This week the international scientific community was once again filled with doubts after a publication in the journal SciTech Daily, which receives funding from the Chinese government. In it, it was ensured that the Sky Eye telescope, located in southwestern China, received signals that could belong to an extraterrestrial civilization. But hours later the post disappearedsomething that aroused even more suspicion.
The opening article was about telescope detection “Various cases of possible technological traces and extraterrestrial civilizations”but the portal and the Chinese government have not given explanations in this regard.
The most striking part of the case came later, once the original note was deleted, when the magazine republished an article in which it tried to reject the previous one. The new writing refers to the fact that a “Fast Burst Radio” (FRB), something that is common to notice; the strange thing is that this signal pulses “regularly every 16.35 days”.
Fast radio bursts emit enormous volumes of energy in microseconds.
An FRB “is a transient radio pulse of a variable length from a fraction of a millisecond, caused by some mysterious astrophysical process maximum power energy that has not yet been discovered, as he explains.
A fast radio burst background
In March 2021, three mysterious FRBs that occurred when the Universe was still in its youth were detected by the giant 500-meter Chinese FAST radio telescope.
Confirmed as their cosmological origin in 2016, these radios show it they last only a few thousandths of a secondit has the potential to provide information on a wide range of astrophysical problems.
So the doctor Niu Chenhuiof the National Astronomical Observatories of the Chinese Academy of Sciences, discovered three new FRBs with a measurement of high dispersion from the massive Five-hundred-meter Aperture Spherical radio Telescope (FAST) data.
Their findings were published in The letters of the astrophysical diary on March 3.
The discovery indicated that these three FRBs occurred billions of years ago when the Universe was still in its youth. The newly discovered FRBs, along with the first FRB detected by FAST last year, suggest there may be many 120,000 detectable FRB reaching Earth everyday.
At 500 meters in diameter, the team can capture radio waves from distant galaxies, and thus confirm whether there are other species in the Universe.
“We are catching up in terms of data processing and we look forward to further discoveries from FAST, the most sensitive radio telescope in the world, ”Chenhui said in a statement.
Comparing FRB samples from the Parkes telescope and the Australian Square Kilometer Array Pathfinder (ASKAP) telescope, Australian researchers revealed the relationship between fluence (integrated flow) and the dispersion measure of FRBs. The new discovery helps extend this relationship and covers a previously less explored parameter space.
“Combined with simulations, FAST could detect FRBs with redshift greater than 3, which is older than 10 billion years,” Niu said in 2021.
The distribution of scattering measurements from these FRBs was sensitive to the shape of the intrinsic brightness distribution of these cosmic events. “Further FAST discoveries will help reveal the still unknown origin of FRBs,” said the Doctor Li Dicorresponding author of the study and chief scientist of FAST.
