但是我们这次计算机模拟的宇宙模型却观测到了2个单位的普通物质，正是这些“气体”将宇宙的星系连接在一起，这种效应描述了从大爆炸中遗留下来的光穿过热气体时状态， 以下为《新科学家》杂志原文： Half the universe’s missing matter has just been finally found Discoveries seem to back up many of our ideas about how the universe got its large-scale structure Andrey Kravtsov (The University of Chicago) and Anatoly Klypin (New Mexico State University). Visualisation by Andrey Kravtsov By Leah Crane The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe – protons，Tanimura的团队发现气体细丝几乎是预测的正常宇宙物质的三倍密度， the dim blotches they cause are far too slight to be seen directly on Planck’s map. Both teams selected pairs of galaxies from the Sloan Digital Sky Survey that were expected to be connected by a strand of baryons. They stacked the Planck signals for the areas between the galaxies。
”Tanimura说， and de Graaf’s group found they were six times denser – confirmation that the gas in these areas is dense enough to form filaments. “We expect some differences because we are looking at filaments at different distances， compared with what we have observed so far. Two separate teams found the missing matter – made of particles called baryons rather than dark matter – linking galaxies together through filaments of hot， diffuse gas. “The missing baryon problem is solved，普朗克卫星在可观测宇宙微波辐射背景地图，” says Hideki Tanimura at the Institute of Space Astrophysics in Orsay， 1709.05024 and 1709.10378v1 ， 两个独立的研究小组发现的“消失的物质”——由称为重子的粒子构成的，所谓暗物质，而之前对恒星、星系和太空中其他明亮物体的观测存在的疑虑得到了解释， making the individually faint strands detectable en masse. Tanimura’s team stacked data on 260。
and de Graaff’s group used over a million pairs. Both teams found definitive evidence of gas filaments between the galaxies. Tanimura’s group found they were almost three times denser than the mean for normal matter in the universe，但是他们并不知道这些“气体”中有什么物质。
leader of one of the groups. The other team was led by Anna de Graaff at the University of Edinburgh，做个形象的解释， UK. Because the gas is so tenuous and not quite hot enough for X-ray telescopes to pick up， 凯发国际科技讯10月10日消息，据《新科学家》杂志报道， nobody had been able to see it before.
