Arguments for an , low H0, baryon dominated universe

Recent results from studies of galaxy clustering in galaxy redshift surveys have tentatively suggested the existence of ‘spike’ features in the galaxy 2-point correlation function at large spatial scales. These features are most straightforwardly predicted in a dense, baryon dominated world model with initial adiabatic fluctuations. Here we discuss the prospects for such a model assuming a Friedmann cosmology with the density parameter, Ω , equal to the critical value of unity. We conclude that the lower the value of Hubble's constant, H 0 , the more likely it is that the above model may be consistent with the current observational constraints.
