So far the farthest galaxy cluster coincided with the star of the birth tide – technology – People’s wetnwild

So far the farthest galaxies in the star birth of "tide" — science and technology — people.com.cn original title: by far the most far galaxies as star birth of "tide" CL J1001+0220 cluster technology daily September 1 Beijing Xinhua (reporter Liu Xia) according to the U.S. National Aeronautics and Space Administration (NASA) official website news, the French scientists use telescope provided the data found so far the most distant galaxies, it emits light through a long journey of about 11 billion 100 million light-years, eventually capturing human. Although the galaxy cluster is young, it is going through the "birth tide" of the star, which will help to better understand the formation of the galaxy cluster and its internal galaxy. The cluster of galaxies consists of more than a dozen galaxies bound together by gravity. The latest "appearance" of the galaxy cluster called "CL J1001+0220", the discovery of the galaxy cluster formation time pushed about 700 million years ago. The person in charge, the French new energy and Atomic Energy Commission (CEA) Wang Tao (transliteration) said: "this cluster has attracted great attention, not only because of the distance between the earth, but also because of the development stage it is undergoing a totally different." The core of the new cluster contains 11 massive galaxies, including 9 galaxies with incredible speed in a star — each year about more than 3 thousand sunlike stars "was born". Study co-author, CEA David? Elbaz said: "we detected the cluster is in a critical period — from the original into a cluster of galaxies, scientists have previously only in the more distant places found in the original cluster." The team compared the latest results with other scientists’ computer simulations of galaxy formation and found that the stellar mass of the new system is very large. This may indicate that distant galaxies in the star formation rate faster than simulation; or such clusters are extremely rare, that scientists in the simulation by far the largest cosmology was found in its "disappeared". Co author of the study, University of Helsinki Alexis? Feinuogenuowei said: "through the study of this object, we can better understand the formation of galaxies and contains galaxies, we hope to find more of these galaxies." Study in August 30th "network" edition of the Astrophysical Journal which is published, the conclusion is derived based on the data provided by the telescope, XMM- Newton telescope telescope, including Chandra NASA’s Harbert space telescope, the Spitzer space telescope, the European Space Agency and the European Southern Observatory’s very large telescope (VLT) etc..
