Quasi-spherical superclusters
Pekka Heinämäki, Pekka Teerikorpi, Marian Douspis +5
Generally the dynamical state of superclusters is poorly known. We study properties of superclusters and select a sample of quasi-spherical superclusters, the dynamics of which can…
The evolution of high-density cores of the BOSS Great Wall superclusters
Maret Einasto, Peeter Tenjes, Mirt Gramann +6
High-density cores (HDCs) of galaxy superclusters that embed rich clusters and groups of galaxies are the earliest large objects to form in the cosmic web, and the largest objects…
Supercluster A2142 and collapse in action - infalling and merging groups and galaxy transformations
Maret Einasto, Mirt Gramann, Changbom Park +8
We study the dynamical state and properties of galaxies and groups in the supercluster SClA2142 that has a collapsing core, to understand its possible formation and evolution. We f…
Infalling groups and galaxy transformations in the cluster A2142
Maret Einasto, Boris Deshev, Heidi Lietzen +7
We study galaxy populations and search for possible merging substructures in the rich galaxy cluster A2142. Normal mixture modelling revealed in A2142 several infalling galaxy grou…
BOSS Great Wall: morphology, luminosity, and mass
Maret Einasto, Heidi Lietzen, Mirt Gramann +7
We study the morphology, luminosity and mass of the superclusters from the BOSS Great Wall (BGW), a recently discovered very rich supercluster complex at the redshift . W…
Sloan Great Wall as a complex of superclusters with collapsing cores
Maret Einasto, Heidi Lietzen, Mirt Gramann +6
In the cosmic web, galaxy superclusters or their high-density cores are the largest objects that may collapse at present or during the future evolution. We study the dynamical stat…
