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…
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…
Analysis of the Interaction Effects in the Southern Galaxy Pair Tol1238-364 and ESO381-G009
S. Temporin, S. Ciroi, P. Rafanelli +4
In the context of the connection among galaxy-galaxy interaction, starbursts and nuclear activity, we present and discuss a quantitative morphological analysis based on BVR images…
Clusters and Superclusters in the Las Campanas Redshift Survey
J. Einasto, M. Einasto, G. H"utsi +6
Two-dimensional high-resolution density field of galaxies of the Las Campanas Redshift Survey (LCRS) with a smoothing length 0.8 Mpc/h is used to extract clusters and groups of gal…
