DETERMINATION OF THE HUBBLE CONSTANT USING A TWO-PARAMETER LUMINOSITY CORRECTION FOR TYPE Ia SUPERNOVAE
In this paper, we make a comprehensive determination of the Hubble constant H0 by using two parameters—the B − V color and the rate of decline ∆m15—to simultaneously standardize the luminosities of all nearby Cepheid-calibrated type Ia supernovae (SNe Ia) and those of a larger, more distant sample of 29 SNe Ia. Each group is treated in as similar a manner as possible in order to avoid systemati...
متن کاملConstraints from Hubble Parameter versus Redshift Data
We use the Simon, Verde, & Jimenez (2005) determination of the redshift dependence of the Hubble parameter to constrain cosmological parameters in three dark energy cosmological models. We consider the standard ΛCDM model, the XCDM parameterization of the dark energy equation of state, and a slowly rolling dark energy scalar field with an inverse power-law potential. The constraints are restric...
متن کاملTYPE Ia SUPERNOVAE AND THE HUBBLE CONSTANT
The focus of this review is the work that has been done during the 1990s on using Type Ia supernovae (SNe Ia) to measure the Hubble constant (H0). SNe Ia are well suited for measuring H0. A straightforward maximum–light color criterion can weed out the minority of observed events that are either intrinsically subluminous or substantially extinguished by dust, leaving a majority subsample that h...
متن کاملCosmological parameter estimation with large scale structure and supernovae data
Most cosmological parameter estimations are based on the same set of observations and are therefore not independent. Here, we test the consistency of parameter estimations using a combination of large-scale structure and supernovae data, without cosmic microwave background (CMB) data. We combine observations from the IRAS 1.2 Jy and Las Campanas redshift surveys, galaxy peculiar velocities and ...
