In the distant universe, almost 13 billion light years away, there is a special type of galaxy. Due to the dust cover and the distance from us, such galaxies are so faint that it is difficult for the Hubble Space Telescope to find them. With the help of NASA's Spitzer infrared space telescope, only four such super-red galaxies were discovered for the first time. Astronomers can describe the characteristics of members of these new "species", but they cannot explain why they are so popular. The research findings of Dr. Huang Jiasheng of the Harvard-Smithsonian Astrophysics Research Center and the researcher Zheng Xianzhong of the Purple Mountain Observatory of the Chinese Academy of Sciences and other collaborators have been published online in the Astrophysical Journal. The research team is a participant of the Spitzer Infrared Space Telescope Large Field International Cooperation Project (SEDS) for deep field surveys outside the Milky Way. They used the observation data of the project and the Hubble Space Telescope Universe Origins Near-Infrared Deep Field Survey Project (CANDELS) to discover these super-red galaxies. "We have to use the most extreme model to explain our observations." Huang Jiasheng said. There are several reasons why galaxies are so red: they may be dust-rich; there may also be many old red stars; or they may look very distant due to the redshift effect. These three factors seem to be reflected in these newly discovered galaxies. These four galaxies exist in the same galaxy group, rather than happening to be distributed in the same area. Given that they are very far away from us, the light we see is emitted by them one billion years after the Big Bang, and it is also a period when the first generation of galaxies was formed. Compared with the Hubble Space Telescope, the Spitzer Infrared Space Telescope is more suitable for observing signals in the infrared band whose wavelength exceeds visible light. The brightness of the newly discovered super-red galaxy in the infrared band is more than 60 times higher than the brightness of the most red band in the Hubble Space Telescope's operating wavelength range. "The Hubble Space Telescope has detected some first-generation primitive galaxies, but it is completely different from this type of super-red galaxies. In a sense, these super-red galaxies may be a missing link in the evolution of galaxies." Zheng Xianzhong The researcher explained. They may be "ancient ancestors" of giant galaxies in our neighboring universe, and are of great significance for understanding how the early galaxies of the universe formed. Next, the research team hopes to measure the precise red shift of these objects, which requires large millimeter-wave telescopes or interferometric arrays (such as ALMA) with more powerful observation capabilities; at the same time, it plans to find more examples of super-red galaxies. Researcher Zheng Xianzhong said, "There is evidence that super-red galaxies also exist in other celestial regions. We will analyze more observation data from Spitzer and Hubble Space Telescope to find them."
