Cepheid Calibrations of Modern Type Ia Supernovae:Implications for the Hubble Constant
Adam G. Riess, Lucas Macri, Weidong Li +9
This is the first of two papers reporting measurements from a program to determine the Hubble constant to 5% precision from a refurbished distance ladder. We present new observatio…
Type Ia supernova science 2010-2020
D. A. Howell, A. Conley, M. Della Valle +47
In the next decade Type Ia supernovae (SNe Ia) will be used to test theories predicting changes in the Dark Energy equation of state with time. Ultimately this requires a dedicated…
Improved Dark Energy Constraints from ~100 New CfA Supernova Type Ia Light Curves
Malcolm Hicken, W. Michael Wood-Vasey, Stephane Blondin +5
We combine the CfA3 supernova Type Ia (SN Ia) sample with samples from the literature to calculate improved constraints on the dark energy equation of state parameter, w. The CfA3…
CfA3: 185 Type Ia Supernova Light Curves from the CfA
Malcolm Hicken, Peter Challis, Saurabh Jha +5
We present multi-band photometry of 185 type-Ia supernovae (SN Ia), with over 11500 observations. These were acquired between 2001 and 2008 at the F. L. Whipple Observatory of the…
