This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
A new method of measuring the cluster peculiar velocity power spectrum
Pengjie Zhang, Hume A. Feldman, Roman Juszkiewicz +1
We propose to use spatial correlations of the kinetic Sunyaev-Zeldovich (KSZ) flux as an estimator of the peculiar velocity power spectrum. In contrast with conventional techniques…
A Test of the Copernican Principle
R. R. Caldwell, A. Stebbins
The blackbody nature of the cosmic microwave background (CMB) radiation spectrum is used in a modern test of the Copernican Principle. The reionized universe serves as a mirror to…
The Mass Of The Coma Cluster From Weak Lensing In The Sloan Digital Sky Survey
Jeffrey M. Kubo, Albert Stebbins, James Annis +4
We present a weak lensing analysis of the Coma Cluster using the Sloan Digital Sky Survey (SDSS) Data Release Five. Complete imaging of a ~ 200 square degree region is used to meas…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
CMB Spectral Distortions from the Scattering of Temperature Anisotropies
Albert Stebbins
Thomson scattering of CMBR temperature anisotropies will cause the spectrum of the CMBR to differ from blackbody even when one resolves all anisotropies. A formalism for computing…
Cosmological Constraints from the SDSS Luminous Red Galaxies
M Tegmark, D Eisenstein, M Strauss +64
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…
Constraining Dark Energy with the Dark Energy Survey: Theoretical Challenges
James Annis, Sarah Bridle, Francisco J. Castander +14
The Dark Energy Survey (DES) will use a new imaging camera on the Blanco 4-m telescope at CTIO to image 5000 square degrees of sky in the South Galactic Cap in four optical bands,…
Dark Energy Studies: Challenges to Computational Cosmology
James Annis, Francisco J. Castander, August E. Evrard +12
The ability to test the nature of dark mass-energy components in the universe through large-scale structure studies hinges on accurate predictions of sky survey expectations within…
Probing Dark Energy via Weak Gravitational Lensing with the SuperNova Acceleration Probe (SNAP)
SNAP Collaboration
SNAP is a candidate for the Joint Dark Energy Mission (JDEM) that seeks to place constraints on the dark energy using two distinct methods. The first, Type Ia SN, is discussed in a…
A new method of measuring the peculiar velocity power spectrum
Pengjie Zhang, Albert Stebbins, Roman Juszkiewicz +1
We show that by directly correlating the cluster kinetic Sunyaev Zeldovich (KSZ) flux, the cluster peculiar velocity power spectrum can be measured to accuracy by future…
The Third Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through June 2003, includes imaging data in five bands ov…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
Isolating Geometry in Weak Lensing Measurements
Jun Zhang, Lam Hui, Albert Stebbins
Given a foreground galaxy-density field or shear field, its cross-correlation with the shear field from a background population of source galaxies scales with the source redshift i…
