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…
Looking Into the Fireball: ROTSE-III and Swift Observations of Early GRB Afterglows
E. S. Rykoff, F. Aharonian, C. W. Akerlof +21
We report on a complete set of early optical afterglows of gamma-ray bursts (GRBs) obtained with the ROTSE-III telescope network from March 2005 through June 2007. This set is comp…
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…
Type II Supernovae as Probes of Cosmology
Dovi Poznanski, Eddie Baron, Stephane Blondin +26
- Constraining the cosmological parameters and understanding Dark Energy have tremendous implications for the nature of the Universe and its physical laws. - The pervasive limit of…
Detection of GRB 060927 at z = 5.47: Implications for the Use of Gamma-Ray Bursts as Probes of the End of the Dark Ages
A. E. Ruiz-Velasco, H. Swan, E. Troja +54
We report on follow-up observations of the GRB 060927 using the ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detected 20 s…
