WebBasic Ly α forest statistics for each z-bin of our data sample. The Ly α forest data is taken from QSO rest wavelengths 1070 Å ≤λ ≤ 1190 Å. N is the number of QSOs contributing to that bin. A given QSO can contribute to 1, 2, or 3 bins, since the maximum z range covered by a spectrum at QSO rest wavelengths 1070–1190 increases from 0.28 Web6 oct. 2005 · We address some of the uncertainties in the theoretical modelling of the Lyman-$\alpha$ forest structures such as the difference between full hydro-dynamical …

Each side of the box measures 30 million light-years across. Much remains unknown about the Lyman-alpha forest, including the real geometry and extent of the clouds, and why there are so many fewer clouds today. chowder tv series panini
