Determining the Amplitude of Mass Fluctuations in the Universe
Xiaohui Fan, Neta A. Bahcall, Renyue Cen
We present a method for determining the rms mass fluctuations on 8 h^-1 Mpc scale, sigma8. The method utilizes the rate of evolution of the abundance of rich clusters of galaxies.…

Constraining Omega with Cluster Evolution
Neta A. Bahcall, Xiaohui Fan, Renyue Cen
We show that the evolution of the number density of rich clusters of galaxies breaks the degeneracy between Omega (the mass density ratio of the universe) and sigma_{8} (the normal…
