The Second Data Release of the Sloan Digital Sky Survey
(IOP Publishing, 2004)
The Sloan Digital Sky Survey (SDSS) has validated and made publicly available its Second Data Release. This data release consists of 3324 deg2 of five-band (ugriz) imaging data with photometry for over 88 million unique ...
Near-Infrared Photometry and Spectroscopy of L and T Dwarfs: The Effects of Temperature, Clouds, and Gravity
(IOP Publishing, 2004)
We present new JHK photometry on the MKO-NIR system and JHK spectroscopy for a large sample of L and T dwarfs. Photometry has been obtained for 71 dwarfs, and spectroscopy for 56. The sample comprises newly identified very ...
Sloan Digital Sky Survey Imaging of Low Galactic Latitude Fields: Technical Summary and Data Release
(IOP Publishing, 2004)
The Sloan Digital Sky Survey (SDSS) mosaic camera and telescope have obtained five-band optical-wavelength imaging near the Galactic plane outside of the nominal survey boundaries. These additional data were obtained during ...
Microwave Interstellar Medium Emission Observed by theWilkinson Microwave Anisotropy Probe
(IOP Publishing, 2004)
We investigate the nature of the diffuse Galactic emission in the Wilkinson Microwave Anisotropy Probe (WMAP) temperature anisotropy data. Substantial dust-correlated emission is observed at all WMAP frequencies, far ...
The Three‐Dimensional Power Spectrum of Galaxies from the Sloan Digital Sky Survey
(IOP Publishing, 2004)
We measure the large-scale real-space power spectrum P(k) by using a sample of 205,443 galaxies from the Sloan Digital Sky Survey, covering 2417 effective square degrees with mean redshift z ≈ 0.1. We employ a matrix-based ...
The DEEP2 Galaxy Redshift Survey: Clustering of Galaxies in Early Data
(IOP Publishing, 2004)
We measure the two-point correlation function ξ(rp, π) in a sample of 2219 galaxies between z = 0.7 and 1.35 to a magnitude limit of RAB = 24.1 from the first season of the DEEP2 Galaxy Redshift Survey. From ξ(rp, π) we ...
Microwave Interstellar Medium Emission in the Green Bank Galactic Plane Survey: Evidence for Spinning Dust
(IOP Publishing, 2004)
We observe significant dust-correlated emission outside of H II regions in the Green Bank Galactic Plane Survey (-4° < b < 4°) at 8.35 and 14.35 GHz. The rising spectral slope rules out synchrotron and free-free emission ...
The V1647 Orionis (IRAS 05436–0007) Protostar and Its Environment
(IOP Publishing, 2004)
We present Sloan Digital Sky Survey (SDSS) and United States Naval Observatory (USNO) observations of the V1647 Ori protostar and its surrounding field near NGC 2068. V1647 Ori, the likely driving source for HH 23, brightened ...
Cosmological parameters from SDSS and WMAP
(American Physical Society (APS), 2004)
We measure cosmological parameters using the three-dimensional power spectrum P(k) from over 200,000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with WMAP and other data. Our results are consistent with ...
Determining Foreground Contamination in Cosmic Microwave Background Observations: Diffuse Galactic Emission in the MAXIMA‐I Field
(IOP Publishing, 2004)
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 contaminating source is known from observations ...
