Microwave ISM Emission Observed by WMAP
Douglas P. Finkbeiner
We investigate the nature of the diffuse Galactic emission in the Wilkinson Microwave Anisotropy Probe (WMAP) temperature anisotropy data. Substantial dust-correlated emission is o…
The 3D power spectrum of galaxies from the SDSS
M Tegmark, M Blanton, M Strauss +32
We measure the large-scale real-space power spectrum P(k) using a sample of 205,443 galaxies from the Sloan Digital Sky Survey, covering 2417 square degrees with mean redshift z~0.…
Microwave Emission from Aligned Dust
A. Lazarian, D. Finkbeiner
Polarized microwave emission from dust is an important foreground that may contaminate polarized CMB studies unless carefully accounted for. We discuss potential difficulties assoc…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
The DEEP2 Galaxy Redshift Survey: Spectral classification of galaxies at z~1
Darren S. Madgwick, Alison L. Coil, Christopher J. Conselice +15
We present a Principal Component Analysis (PCA)-based spectral classification, eta, for the first 5600 galaxies observed in the DEEP2 Redshift Survey. This parameter provides a ver…
The DEEP2 Galaxy Redshift Survey: Clustering of Galaxies in Early Data
Alison L. Coil, Marc Davis, Darren S. Madgwick +14
We measure the two-point correlation function xi(r) using a sample of 2219 galaxies in an area of 0.32 degrees^2 at z=0.7-1.35 from the first season of the DEEP2 Galaxy Redshift Su…
The velocity dispersion function of early-type galaxies
Ravi K. Sheth, M. Bernardi, P. L. Schechter +12
The distribution of early-type galaxy velocity dispersions, phi(sigma), is measured using a sample drawn from the SDSS database. Its shape differs significantly from that which one…
Early-type galaxies in the SDSS. I. The sample
M. Bernardi, R. K. Sheth, J. Annis +7
A sample of nearly 9000 early-type galaxies, in the redshift range 0.01 < z < 0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral criteria. This pa…
Early-type galaxies in the SDSS. III. The Fundamental Plane
M. Bernardi, R. K. Sheth, J. Annis +7
A magnitude limited sample of nearly 9000 early-type galaxies, in the redshift range 0.01 < z < 0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral…
Early-type galaxies in the SDSS. II. Correlations between observables
M. Bernardi, R. K. Sheth, J. Annis +7
A magnitude limited sample of nearly 9000 early-type galaxies, in the redshift range 0.01 < z < 0.3, was selected from the Sloan Digital Sky Survey using morphological and spectral…
A Full-Sky H-alpha Template for Microwave Foreground Prediction
Douglas P. Finkbeiner
A full-sky H-alpha map with 6 arcmin (FWHM) resolution is presented. This map is a composite of the Virginia Tech Spectral line Survey (VTSS) in the north and the Southern H-Alpha…
Determining Foreground Contamination in CMB Observations: Diffuse Galactic Emission in the MAXIMA-I Field
A. H. Jaffe, A. Balbi, J. R. Bond +11
Observations of the CMB can be contaminated by diffuse foreground emission from sources such as Galactic dust and synchrotron radiation. In these cases, the morphology of the conta…
