Earlier this year, scientists identified some dark matter filaments for the first time. According to the physicist organization network on October 17 (Beijing time), recently, an astronomical team composed of researchers from many countries in France, the United States and Other countries began to probe these filament structures from a three-dimensional perspective to eliminate common mistakes when studying floor plans Help to further reveal the true nature of the universe. The cosmic web constitutes the large-scale structure of the universe, and the dark matter filaments are part of it, and are also the remnants of the initial moment after the Big Bang. The Big Bang theory predicts that the uneven material density at the initial moment of the universe has caused the bulk of the material to become dense and condense into a entangled wire mesh. Computer-simulated cosmic evolution also supports this view, which shows that the structure of the universe is like a net, with long filaments connected to each other, and the connection point is located in the position of a massive galaxy group. Although these filaments are very large, they are mainly composed of dark matter, and it is extremely difficult to see them. The research team analyzed the high-resolution images of MACS J0717.5 + 3745 in the area around the massive mass of galaxies. MACS J0717 is also one of the most massive galaxies known. The images used are from the Hubble Telescope, the Japan National Observatory Subaru Telescope, and the Canada-France-Hawaii Telescope, and combine the spectral data of the WM Keck Observatory and the Gemini Observatory to the interior of the galaxy. After a comprehensive analysis of the image and data, a complete picture of the dark matter filament is constructed: it extends from the core of the galaxy group and spans 60 million light years. "Cosmic web filaments are huge and very scattered, and it is extremely difficult to detect them." The leading author of the paper, the French Marseille Astrophysics Laboratory (LAM) and Matilde of KwaZulu-Natal University in South Africa Jean Zach said that studying them requires combining many key factors. First, there must be a most likely goal. Cosmic evolution theory shows that galaxy clusters are formed where the filaments of the cosmic web meet, and these filaments slowly inject matter into the galaxy cluster. "According to our early research on MACS J0717, these galaxies are found to be actively growing, so detailed study of the cosmic web has become one of our main goals." Harold Ebelin, the co-author of the paper and the University of Hawaii at the United States, said. The research team he led discovered MACS J0717 10 years ago. The second is advanced gravitational lens technology. Most of the cosmic web filaments are composed of dark matter, and the mass is large enough to bend the light and deform the background galaxy image. This phenomenon is called the gravitational lens effect. Studying this tiny deformation can in turn reveal the hidden location of dark matter filaments. They have developed new tools that can transform deformed galaxy images into quality maps. Then the resolution of the image should be high enough to study the subtle lens effect; the last is to measure distance and motion. The co-author of the paper, French LAM Jean-Bauer Carnebé, said that the current challenge is to find a model of the shape of a galaxy group, suitable for all the characteristics of the lens effect observed. Combined with the position and velocity information, the three-dimensional structure and direction of the dark matter filaments can be revealed, and the deviation and uncertainty caused by the two-dimensional image can be eliminated. The researchers pointed out that these results help to push the limits of model prediction. The James Webb Telescope scheduled for launch in 2018 will also use its highly sensitive characteristics to become a powerful tool for detecting the filaments of the cosmic web.
