Luminous Red Galaxy Halo Density Field Reconstruction and Application to Large Scale Structure Measurements
Beth A. Reid, David N. Spergel, Paul Bode
The complex relationship between the galaxy density field and the underlying matter field limits our ability to extract cosmological constraints from galaxy redshift surveys. Our a…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Bayesian Estimation of CMB Polarization Maps
J. Dunkley, D. N. Spergel, E. Komatsu +17
We describe a sampling method to estimate the polarized CMB signal from observed maps of the sky. We use a Metropolis-within-Gibbs algorithm to estimate the polarized CMB map, cont…
Measuring Distance Ratios with CMB-Galaxy Lensing Cross-correlations
Sudeep Das, David N. Spergel
We propose a method for cosmographic measurements by combining gravitational lensing of the cosmic microwave background (CMB) with cosmic shear surveys. We cross-correlate the gala…
Constraining the LRG Halo Occupation Distribution using Counts-in-Cylinders
Beth A. Reid, David N. Spergel
The low number density of the Sloan Digital Sky Survey (SDSS) Luminous Red Galaxies (LRGs) suggests that LRGs occupying the same dark matter halo can be separated from pairs occupy…
Efficient Power Spectrum Estimation for High Resolution CMB Maps
Sudeep Das, Amir Hajian, David N. Spergel
Estimation of the angular power spectrum of the Cosmic Microwave Background (CMB) on a small patch of sky is usually plagued by serious spectral leakage, specially when the map has…
CMB Lensing and the WMAP Cold Spot
Sudeep Das, David N. Spergel
Cosmologists have suggested a number of intriguing hypotheses for the origin of the "WMAP cold spot", the coldest extended region seen in the CMB sky, including a very large void a…
Improving Photometric Redshifts using GALEX Observations for the SDSS Stripe 82 and the Next Generation of SZ Cluster Surveys
Michael D. Niemack, Raul Jimenez, Licia Verde +3
Four large-area Sunyaev-Zeldovich (SZ) experiments -- APEX-SZ, SPT, ACT, and Planck -- promise to detect clusters of galaxies through the distortion of Cosmic Microwave Background…
Next Generation Redshift Surveys and the Origin of Cosmic Acceleration
Viviana Acquaviva, Amir Hajian, David N. Spergel +1
Cosmologists are exploring two possible sets of explanations for the remarkable observation of cosmic acceleration: dark energy fills space or general relativity fails on cosmologi…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Data Processing, Sky Maps, and Basic Results
G. Hinshaw, J. L. Weiland, R. S. Hill +18
We present new full-sky temperature and polarization maps in five frequency bands from 23 to 94 GHz, based on data from the first five years of the WMAP sky survey. The five-year m…

We present the temperature and polarization angular power spectra of the cosmic microwave background (CMB) derived from the first 5 years of WMAP data. The 5-year temperature (TT)…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Likelihoods and Parameters from the WMAP data

Cosmology and other scientific results from the WMAP mission require an accurate knowledge of the beam patterns in flight. While the degree of beam knowledge for the WMAP one-year…
Five-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Cosmological Interpretation
E. Komatsu, J. Dunkley, M. R. Nolta +16
(Abridged) The WMAP 5-year data strongly limit deviations from the minimal LCDM model. We constrain the physics of inflation via Gaussianity, adiabaticity, the power spectrum shape…
