Riess, Adam G., Macri, Lucas, Casertano, Stefano, Sosey, Megan, Lampeitl, Hubert, Ferguson, Henry C., ...
We report observations of 240 Cepheid variables obtained with the Near Infrared Camera (NICMOS) through the F160W filter on the Hubble Space Telescope (HST). The Cepheids are distributed across six...
Cepheid Calibrations of Modern Type Ia Supernovae:Implications for the Hubble Constant (2009)
Riess, Adam G., Macri, Lucas, Li, Weidong, Lampeitl, Hubert, Casertano, Stefano, Ferguson, Henry C., ...
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 observations of 110 Cepheid...
Luminosity Indicators in the Ultraviolet Spectra of Type Ia Supernovae (2008)
Foley, Ryan J., Filippenko, Alexei V., Jha, Saurabh W.
We present a complete sample of International Ultraviolet Explorer and Hubble Space Telescope ultraviolet (UV) spectra of Type Ia supernovae (SNe Ia) through 2004. We measure the equivalent width...
