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…
"An Era of Precision Astrophysics: Connecting Stars, Galaxies and the Universe," an Astro2010 Science White Paper
Rob P. Olling, Ron J. Allen, Jay Anderson +14
Abridged: The golden age of astrophysics is upon us with both grand discoveries (extra-solar planets, dark matter, dark energy) and precision cosmology. Fundamental understanding o…
Distance to NGC 0247
Barry F. Madore, Wendy L. Freedman, J. Catanzarite +1
We report VRI CCD observations of nine Cepheids in the South Polar (Sculptor) Group spiral galaxy NGC 0247. Periods of these Cepheids range from 20 to 70 days. Over the past 20 yea…
The Peculiar SN 2005hk: Do Some Type Ia Supernovae Explode as Deflagrations?
M. M. Phillips, W. Li, J. A. Frieman +41
We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002…
Report of the Dark Energy Task Force
Andreas Albrecht, Gary Bernstein, Robert Cahn +10
Dark energy appears to be the dominant component of the physical Universe, yet there is no persuasive theoretical explanation for its existence or magnitude. The acceleration of th…
