Variable Sodium Absorption in a Low-Extinction Type Ia Supernova
Joshua D. Simon, Avishay Gal-Yam, Orly Gnat +18
Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but…
Findings of the Joint Dark Energy Mission Figure of Merit Science Working Group
Andreas Albrecht, Luca Amendola, Gary Bernstein +8
These are the findings of the Joint Dark Energy Mission (JDEM) Figure of Merit (FoM) Science Working Group (SWG), the FoMSWG. JDEM is a space mission planned by NASA and the DOE fo…
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…
