Estimating the Large-Scale Structure of the Universe Using Quasi-Stellar Object Carbon IV Absorbers
利用类星体碳 IV 吸收体估计宇宙大尺度结构
Galaxies have long been known to form large clusters, and cosmologists are interested in characterizing this clustering as a way of studying the large-scale structure of the universe. This work is motivated by a data catalog consisting of information on lines of sight from Earth to distant quasi-stellar objects (QSO's) and the carbon IV absorbers that lie on them. The absorbers are believed to be gas clouds near galaxies too far away to be easily observed. Thus, the absorber…
