Hi all, For this week's seminar on Friday we have Roger Clowes, who will speaking about: The largest features of the early universe: a re-examination of the Clowes & Campusano Large Quasar Group with the SDSS At the time of its discovery the Clowes & Campusano Large Quasar Group (LQG) at <z> = 1.28 was the largest feature known in the early universe. This seminar will report on the status of LQGs in general and, in particular, on what can now be learnt about the Clowes & Campusano LQG by re-examining it with the new data provided by the SDSS quasar database. Some interesting properties of its cosmological neighbourhood will also be discussed. The seminar starts at 12 noon in Huxley 503, followed by lunch with the speaker. See you there!
