This paper describes the Sixth Data Release of the Sloan Digital Sky Survey. With this data release, the imaging of the northern Galactic cap is now complete. The survey contains images and…
Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples
- M. Betoule, R. Kessler, C. Wheeler
- Physics
- 16 January 2014
Aims. We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The dataset includes several low-redshift…
Cosmological constraints from the SDSS luminous red galaxies
- Max Tegmark, D. Eisenstein, D. York
- Physics
- 30 August 2006
We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints on cosmological…
FIRST-YEAR SLOAN DIGITAL SKY SURVEY-II SUPERNOVA RESULTS: HUBBLE DIAGRAM AND COSMOLOGICAL PARAMETERS
- R. Kessler, A. Becker, D. York
- Physics
- 28 August 2009
We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital Sky Survey-II…
Inflation dynamics and reheating
- B. Bassett, S. Tsujikawa, D. Wands
- Physics
- 27 July 2005
The theory of inflation with single and multiple fields is reviewed paying particular attention to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the primary means of…
Adiabatic and entropy perturbations from inflation
- C. Gordon, D. Wands, B. Bassett, R. Maartens
- Physics, Environmental Science
- 8 September 2000
We study adiabatic ~curvature! and entropy ~isocurvature! perturbations produced during a period of cosmological inflation that is driven by multiple scalar fields with an arbitrary interaction…
THE RISE AND FALL OF TYPE Ia SUPERNOVA LIGHT CURVES IN THE SDSS-II SUPERNOVA SURVEY
- B. Hayden, P. Garnavich, J. Sollerman
- Physics
- 19 January 2010
We analyze the rise and fall times of Type Ia supernova (SN Ia) light curves discovered by the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. From a set of 391 light curves k-corrected to…
THE SLOAN DIGITAL SKY SURVEY-II SUPERNOVA SURVEY: TECHNICAL SUMMARY
- J. Frieman, B. Bassett, D. York
- Physics
- 21 August 2007
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) using…
THE EFFECT OF HOST GALAXIES ON TYPE Ia SUPERNOVAE IN THE SDSS-II SUPERNOVA SURVEY
- H. Lampeitl, Mathew Smith, M. Stritzinger
- Physics
- 25 May 2010
We present an analysis of the host galaxy dependences of Type Ia Supernovae (SNe Ia) from the full three year sample of the SDSS-II Supernova Survey. We re-discover, to high significance, the strong…
