Type Ia Supernovae and the Value of the Hubble Constant
The methodology involved in deriving the Hubble Constant via the calibration of the corrected peak luminosities of Type Ia supernovae (SNe) is reviewed. We first present a re-analysis of the CalánTololo (C-T) and Center for Astrophysics (CfA) Type Ia SN surveys. Bivariate linear least squares and quadratic boot-strapped fits in peak apparent magnitude and light curve shape are employed to corre...
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...

Cepheid calibration of type Ia Supernovae and the Hubble constant
We investigate how a different calibration of the Cepheid Period-Luminosity (PL) relation taking into account the metallicity corrections, affects the absolute magnitude calibration of Supernovae (SNe) Ia and, in turn, the determination of the Hubble constant H0. We exploit SN Ia light curves from literature and previously unpublished data, to build the MB – ∆m15(B) relation and we calibrate th...
متن کاملSupernovae and the Hubble Constant (or Butthead’s Revenge)
RESUMEN Physical models of Type Ia supernovae (SN Ia) that do not depend on secondary calibrators have indicated that the Hubble Constant must be ∼ 65 km s −1 Mpc −1 for well over a decade with the range of uncertainty shrinking with the sophistication of the models. This estimate is in good agreement with those based on HST observations of Cepheid variables and with purely empirical methods ba...
