According to the FAST Project Department of the National Astronomical Observatory of the Chinese Academy of Sciences, FAST, known as China’s “Sky Eye“, detected repeated bursts of fast radio bursts for the first time, capturing the largest number of known pulses in the world.
It is reported that this “mysterious radio signal deep in the universe” is about 3 billion light-years away from the earth.
At present, interference factors such as aircraft and satellites have been eliminated, and cross-validation and further processing of the data are still in progress.
In 2007, humans discovered fast radio bursts for the first time. There are currently less than 100 in total, and they usually appear and then disappear once, making them very mysterious.
In 2015, the Arecibo telescope detected repeated bursts of fast radio burst FRB121002 for the first time. The signal source was located in a dwarf galaxy about 3 billion light-years away from the Earth.
On the morning of August 30, 2019, FAST detected the pulse from FRB121002 for the first time in real time. Since then, it has detected dozens of pulses every day for many consecutive days, and has accumulated a large number of high signal-to-noise ratio pulses. The number of detected pulses is currently The one who knows the most.
FAST, also known as the 500-meter Aperture Spherical Radio Telescope, is located in the karst depression in Dawodang, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. It is a major national scientific and technological infrastructure and has my country’s independent intellectual property rights and is the world’s largest It is the most sensitive radio telescope with a single aperture and its comprehensive performance is 10 times that of the famous radio telescope Arecibo.
As of August 28, 2019, FAST has discovered 132 high-quality pulsar candidates, 93 of which have been confirmed as newly discovered pulsars.
