Pavlov, AnatolyFarooq, OmerRatra, Bharat V.2014-11-062014-11-062014-07-11http://hdl.handle.net/2097/18650We compile a list of 14 independent measurements of a large-scale structure growth rate between redshifts 0.067≤z≤0.8 and use this to place constraints on model parameters of constant and time-evolving general-relativistic dark energy cosmologies. With the assumption that gravity is well modeled by general relativity, we discover that growth-rate data provide restrictive cosmological parameter constraints. In combination with type Ia supernova apparent magnitude versus redshift data and Hubble parameter measurements, the growth rate data are consistent with the standard spatially flat ΛCDM model, as well as with mildly evolving dark energy density cosmological models.en-USThis Item is protected by copyright and/or related rights.
