Equation of state of the photoionized intergalactic medium
We develop an efficient method to study the effects of reionization history on the temperature-density relation of the intergalactic medium in the low density limit (overdensity less than 5). It is
Cosmological parameters from SDSS and WMAP
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
THE THREE-DIMENSIONAL POWER SPECTRUM OF GALAXIES FROM THE SLOAN DIGITAL SKY SURVEY
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.
Probing the Universe with the Lyα forest — I. Hydrodynamics of the low-density intergalactic medium
We introduce an efficient and accurate alternative to full hydrodynamic simulations, Hydro-PM (HPM), for the study of the low column density Lyman-alpha forest (NHI <∼ 10 14 cm−2). It consists of a
Ultralight scalars as cosmological dark matter
Many aspects of the large-scale structure of the Universe can be described successfully using cosmological models in which 27±1% of the critical mass-energy density consists of cold dark matter
How Many Galaxies Fit in a Halo? Constraints on Galaxy Formation Efficiency from Spatial Clustering
We study galaxy clustering in the framework of halo models, where gravitational clustering is described in terms of dark matter halos. At small scales, dark matter clustering statistics are dominated
THE THERMAL MEMORY OF REIONIZATION HISTORY
The recent measurement by WMAP of a large electron-scattering optical depth τe = 0.17 ± 0.04 is consistent with a simple model of reionization in which the intergalactic medium (IGM) is ionized at
Clustering of luminous red galaxies – IV. Baryon acoustic peak in the line-of-sight direction and a direct measurement of H(z)
We study the clustering of luminous red galaxies in the latest spectroscopic Sloan Digital Sky Survey data releases (DR), DR6 and DR7, which sample over 1 Gpc 3 h ―3 to z = 0.47. The two-point
The angular correlation function of galaxies from early sloan digital sky survey data
The Sloan Digital Sky Survey is one of the first multicolor photometric and spectroscopic surveys designed to measure the statistical properties of galaxies within the local universe. In this paper
Effective field theory for hydrodynamics: Thermodynamics, and the derivative expansion
We consider the low-energy effective field theory describing the infrared dynamics of non-dissipative fluids. We extend previous work to accommodate conserved charges, and we clarify the matching
