International leader! Scientists use Chinese Sky Eye FAST to obtain high-definition images of galactic gases

Thanks to CTOnews.com netizen Brother Black fly's left hand clue delivery! CTOnews.com, December 10, according to a CCTV report, the scientific research team of the National Astronomical Observatory of the Chinese Academy of Sciences has used the Chinese celestial eye FAST to obtain the highest sensitivity and clarity of the distribution structure of hydrogen atomic gas in the Milky way, as well as the diffuse characteristics of ionized gas, and the team also identified the remains of two supernova explosions.

These studies are of great significance for understanding the birth of celestial bodies in the Milky way and the material cycle in interstellar space, and the relevant results were published in the professional academic journal Chinese Science on December 10, 2022.

According to reports, the scientific research team of the National Astronomical Observatory of the Chinese Academy of Sciences recently completed the observation of a part of the Milky way using FAST, processed about 44000 radio spectral line data, and obtained the distribution structure of hydrogen atomic gas and the diffuse characteristics of ionized gases in the Milky way with the highest sensitivity and resolution in the world.

His team used pulsars to detect the largest range of magnetic field features in the Milky way to date, and scanned an area of the Milky way using Chinese Sky Eye FAST, and new evidence identified two traces of supernova explosions.

CTOnews.com learned that hydrogen molecular clouds can be formed after the accumulation and cooling of hydrogen atomic gas in the universe, eventually giving birth to a new generation of stars under dense cores, while newborn stars cause the surrounding gas to be ionized, and some of these stars die out to produce supernova remnants and pulsars.

It is worth mentioning that FAST has previously discovered the largest atomic gas structure in the universe, with a scale of about 2 million light-years.
