Evidence for Type Ia Supernova Diversity from Ultraviolet Observations with the Hubble Space Telescope
Xiaofeng Wang, Lifan Wang, Alexei V. Filippenko +93
We present ultraviolet (UV) spectroscopy and photometry of four Type Ia supernovae (SNe 2004dt, 2004ef, 2005M, and 2005cf) obtained with the UV prism of the Advanced Camera for Sur…

Multiphase PC/PL Relations: Comparison between Theory and observations
S. Kanbur, M. Marconi, C. Ngeow +5
Cepheids are fundamental objects astrophysically in that they hold the key to a CMB independent estimate of Hubble's constant. A number of researchers have pointed out the possibil…
