The richest superclusters. II. Galaxy populations
M. Einasto, E. Saar, J. Einasto +9
We study the morphology of galaxy populations of the richest superclusters from the catalogue of superclusters of galaxies in the 2dF Galaxy Redshift Survey using the luminosity de…
Constraining dark energy via baryon acoustic oscillations in the (an)isotropic light-cone power spectrum
Christian Wagner, Volker Müller, Matthias Steinmetz
The measurement of the scale of the baryon acoustic oscillations (BAO) in the galaxy power spectrum as a function of redshift is a promising method to constrain the equation-of-sta…
Las Campanas Loose Groups in the Supercluster-Void Network
M. Einasto, J. Jaaniste, J. Einasto +3
We study the spatial distribution of loose groups from the Las Campanas Redshift Survey, comparing it with the supercluster-void network delineated by rich clusters of galaxies. We…
Large Scale Structures in the Las Campanas Redshift Survey and in Simulations
V. Müller, A. G. Doroshkevich, J. Retzlaff +1
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…
The Supercluster-Void Network. IV. The Shape and Orientation of Superclusters
J. Jaaniste, E. Tago, M. Einasto +3
We present a study of the shape, size, and spatial orientation of superclusters of galaxies. Approximating superclusters by triaxial ellipsoids we show that superclusters are flatt…
