چکیده
We present the rst results of the Karhunen-Lo eve (KL) eigenmodes applied to real data of the Las Campanas Redshift Survey (LCRS) to simultaneously measure the values of the redshift-distortion parameter, = 0:6 0 =b, the linearly extrapolated normalization, L 8 , and the CDM shape parameter, ? = 0 h. The results of our numerical likelihood analysis indicate a low value of = 0:300:39, a shape parameter ? = 0:16 0:10, and a linearly extrapolated normalization L 8 = 0:79 0:08, which are consistent with a low density universe, 0 < 0:5.

Cosmological Parameters from the Eigenmode Analysis of the Las Campanas Redshift Survey.
We present the first results of the Karhunen-Loève eigenmodes applied to real data of the Las Campanas Redshift Survey to simultaneously measure the values of the redshift distortion parameter beta=Omega0.60&solm0;b, the linearly extrapolated normalization sigmaL8, and the cold dark matter shape parameter Gamma=Omega0h. The results of our numerical likelihood analysis indicate a low value of be...
متن کاملLarge Scale Structures in the Las Campanas Redshift Survey and in Simulations
The large supercluster structures obvious in recent galaxy redshift surveys are quantified using an one-dimensional cluster analysis (core sampling) and a three-dimensional cluster analysis based on the minimal spanning tree. The comparison with the LCRS reveals promising stable results. At a mean overdensity of about ten, the supercluster systems form huge wall-like structures comprising about...
متن کاملClustering statistics on a light-cone in the cosmological redshift space
We summarize a series of our recent work concerning the cosmological redshift-space distortion and light-cone effects. After briefly describing the theoretical formalism, we show how those effects are sensitive to the cosmological parameters. Then we apply this formalism to predict the two-point correlation functions and power spectra for the X-ray clusters, galaxies and quasars in future surve...
متن کاملAn Overview of the Las Campanas Distant Cluster Survey
We present the Las Campanas Distant Cluster Survey, which has produced over a thousand galaxy cluster candidates at 0.35 < z < 1.1 (see Gonzalez et al. 2001 for the full catalog). We discuss the technique that enabled us to use short (∼ 3 min) exposures and a small (1m) telescope to efficiently survey ∼ 130 sq. deg. of sky. Follow-up imaging and spectroscopy using a wide array of telescopes inc...
متن کاملLas Campanas Redshift Survey Results: the 3d Power Spectrumand the Luminosity Function
Some recent results on the galaxy 3D power spectrum and the luminosity function derived from the Las Campanas Redshift Survey (LCRS) are discussed. We will present the LCRS power spectrum, compare it against results from other local redshift surveys, and use it to constrain a number of cold dark matter structure formation models. Then we will proceed to describe the LCRS luminosity function, as...
