The Phoenix set has the largest hot, cooling gas reserve among the galaxy clusters. This gas is an important factor that causes the emergence of new stars. In order for the stars to form, the gas needs to cool down and concentrate. The gas in the Phoenix cluster creates stars at an incredible speed. However, the giant black hole in the center of the cluster is a factor that must prevent the formation of stars by pushing the gas away and keeping it warm.
The giant black hole in the Phoenix cluster should keep the gases warm and prevent the formation of stars, while observations show the opposite. James Webb Space Telescope (JWST) Middle-infrared vehicle (MIRI) examined the gas at the center of the Phoenix set in detail. In this way, the cooling gas that contributed to the formation of stars were found to be noticed before. The temperatures of this gas are around 300 thousand degrees. In the gas in the Phoenix cluster, it was found that neon and oxygen atoms were ionized and spread light. Neon emits the oxygen ultraviolet light while spreading infrared light, even though it is weaker. JWST made this discovery by perceiving Neon radiation very clearly.
This method of discovery of JWST can also be used to examine the gases in other galaxy clusters. The team plans to try this method elsewhere.
