(2004b) get good fits to current observational data with their superwind semi-analytic model, in which high constant values of τ* are associated with quiescent (disk) star formation so that most of the stellar mass in giant ellipticals is built up within disks, and simply rearranged into spheroids during mergers.
WebDec 30, 2024 · The first objects to collapse gravitationally after the Big Bang might have been globular cluster-size galaxy pieces, with masses around 10 6 solar masses. Suppose you merge two of those together, then merge two larger pieces together, and so on, Lego-style, until you reach a Milky Way mass, about 10 12 solar masses.
