Euclid. I. Overview of the Euclid mission / Euclid Collaboration
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015-2025 programme of the European Space Agency (ESA) that will provide high-resolution optical imaging, as well as near-infrared imaging and spectroscopy, over about 14,000 deg^2 of extragalactic sky.

Perturbation Theory of the Cosmological Log-Density Field / Wang, Xin (NAOC, Beijing ; Johns Hopkins U. ; Beijing, GUCAS) ; Neyrinck, Mark (Johns Hopkins U.) ; Szapudi, István (Inst. Astron., Honolulu) ; Szalay, Alex (Johns Hopkins U.) ; Chen, Xuelei (NAOC, Beijing ; Peking U., CHEP) ; Lesgourgues, Julien (CERN ; Ecole Polytechnique, Lausanne) ; Riotto, Antonio (CERN ; INFN, Padua) ; Sloth, Martin (CERN)
The matter density field exhibits a nearly lognormal probability density distribution (PDF) after entering into the nonlinear regime. Recently, it has been shown that the shape of the power spectrum of a logarithmically transformed density field is very close to the linear density power spectrum, motivating an analytic study of it. [...]

The 3D Power Spectrum from Angular Clustering of Galaxies in Early SDSS Data / SDSS Collaboration
Early photometric data from the Sloan Digital Sky Survey (SDSS) contain angular positions for 1.5 million galaxies. In companion papers, the angular correlation function $w(\theta)$ and 2D power spectrum $C_l$ of these galaxies are presented. [...]

KL Estimation of the Power Spectrum Parameters from the Angular Distribution of Galaxies in Early SDSS Data / SDSS Collaboration
We present measurements of parameters of the 3-dimensional power spectrum of galaxy clustering from 222 square degrees of early imaging data in the Sloan Digital Sky Survey. The projected galaxy distribution on the sky is expanded over a set of Karhunen-Loeve eigenfunctions, which optimize the signal-to-noise ratio in our analysis. [...]

Galaxy Clustering in Early SDSS Redshift Data / SDSS Collaboration
We present the first measurements of clustering in the Sloan Digital Sky Survey (SDSS) galaxy redshift survey. Our sample consists of 29,300 galaxies with redshifts 5,700 km/s < cz < 39,000 km/s, distributed in several long but narrow (2.5-5 degree) segments, covering 690 square degrees. [...]
