Groups in the Millennium Simulation and in SDSS DR7
P. Nurmi, P. Heinämäki, T. Sepp +6
The Millennium N-body simulation and the Sloan Digital Sky Survey seventh data release (SDSS DR7) galaxy and galaxy group catalogues are compared to study the properties of galaxy…
Multimodality of rich clusters from the SDSS DR8 within the supercluster-void network (talk at MG13 meeting)
M. Einasto
We study the relations between the multimodality of galaxy clusters drawn from the SDSS DR8 and the environment where they reside. We find that multimodal clusters reside in higher…
Multimodality in galaxy clusters from SDSS DR8: substructure and velocity distribution
M. Einasto, J. Vennik, P. Nurmi +8
We search for the presence of substructure, a non-Gaussian, asymmetrical velocity distribution of galaxies, and large peculiar velocities of the main galaxies in galaxy clusters wi…
Groups and clusters of galaxies in the SDSS DR8. Value-added catalogues
E. Tempel, E. Tago, L. J. Liivamägi
Aims. We intend to compile a new galaxy group and cluster sample of the latest available SDSS data, adding several parameter for the purpose of studying the supercluster network, g…
Large scale environments of z<0.4 active galaxies
H. Lietzen, P. Heinämäki, P. Nurmi +5
Properties of galaxies depend on their large-scale environment. As the influence of active galactic nuclei (AGN) in galaxy evolution is becoming more evident, their large scale env…
SDSS DR7 superclusters. Principal component analysis
M. Einasto, L. J. Liivamagi, E. Saar +4
We apply the principal component analysis and Spearman's correlation test to study the properties of superclusters drawn from the SDSS DR7. We analyse possible selection effects in…
