Recovering the real-space correlation function from photometric redshift surveys
Pablo Arnalte-Mur, Alberto Fernández-Soto, Vicent J. Martínez +3
Measurements of clustering in large-scale imaging surveys that make use of photometric redshifts depend on the uncertainties in the redshift determination. We have used light-cone…
Luminous superclusters: remnants from inflation
J. Einasto, M. Einasto, E. Saar +10
We derive the luminosity and multiplicity functions of superclusters compiled for the 2dF Galaxy Redshift Survey, the Sloan Digital Sky Survey (Data Release 4), and for three sampl…
Superclusters of galaxies from the 2dF redshift survey. II. Comparison with simulations
J. Einasto, M. Einasto, E. Saar +10
We investigate properties of superclusters of galaxies found on the basis of the 2dF Galaxy Redshift Survey, and compare them with properties of superclusters from the Millennium S…
Superclusters of galaxies from the 2dF redshift survey. I. The catalogue
J. Einasto, M. Einasto, E. Tago +10
We use the 2dF Galaxy Redshift Survey data to compile catalogues of superclusters for the Northern and Southern regions of the 2dFGRS, altogether 543 superclusters at redshifts 0.0…
Light-cone Simulations: Evolution of dark matter haloes
P. Hein"am"aki, I. Suhhonenko, E. Saar +3
We present a new fast method for simulating pencil-beam type light-cones, using the MLAPM-code (Multi Level Adaptive Particle Mesh) with light-cone additions. We show that by a car…
Clusters and groups of galaxies in the 2dF galaxy redshift survey
E. Tago, J. Einasto, M. Einasto +1
We create a new catalogue of groups and clusters for the 2dF GRS final release sample. We show that the variable linking length friends-of-friends (FoF) algorithms used so far yiel…
Environmental Enhancement of DM Haloes
M. Einasto, I. Suhhonenko, P. Hein"am"aki +2
We study the properties of dark matter haloes of a LCDM model in different environments. Using the distance of the 5th nearest neighbour as an environmental density indicator, we s…
Toward Understanding Environmental Effects in SDSS Clusters
J. Einasto, E. Tago, M. Einasto +5
We find clusters and superclusters of galaxies using the Data Release 1 of the Sloan Digital Sky Survey. We determine the luminosity function of clusters and find that clusters in…
Peculiar velocities of galaxy clusters: a comparison with the linear theory
Mirt Gramann, Ivan Suhhonenko
We investigate peculiar velocities predicted for clusters in Lambda cold dark matter (CDM) models assuming that the initial density fluctuation field is Gaussian. To study the n…
Dynamical state of superclusters of galaxies: do superclusters expand or have they started to collapse?
Mirt Gramann, Ivan Suhhonenko
We investigate the dynamical state of superclusters in Lambda cold dark matter (CDM) cosmological models, where the density parameter and (the rms fluctuatio…
The rms peculiar velocity of galaxy clusters for different cluster masses and radii
Ivan Suhhonenko, Mirt Gramann
We investigate the rms peculiar velocity of galaxy clusters in the Lambda cold dark matter (CDM) and tau cold dark matter (CDM) cosmological models using N-body simulations.…
The Power Spectrum of Clusters of Galaxies and the Press-Schechter Approximation
Mirt Gramann, Ivan Suhhonenko
We examine the power spectrum of clusters in the Press-Schechter (PS) theory and in N-body simulations to see how the power spectrum of clusters is related to the power spectrum of…
Two cosmological models for clusters of galaxies
Ivan Suhhonenko, Mirt Gramann
We investigate the properties of clusters of galaxies in two cosmological models using N-body simulations and the Press-Schecter (PS) theory. In the first model, the initial power…
