pomarede, "Two extraordinary uLSSs (ultra-large-scale structures) in such close configuration raises the possibility that together they form an even more extraordinary cosmological system."
➡️ The #discovery of the Big Ring, the second uLSS found in MgII-absorber catalogues, following the previously reported Giant Arc, is now posted on #arXiv and submitted to #JCAP by @morninglopez, @rgclowes, and G.M. Williger
