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…
To be or not to be: hot WHIM absorption in the blazar PKS 2155-304 sight line?
J. Nevalainen, E. Tempel, J. Ahoranta +8
The cosmological missing baryons at z<1 most likely hide in the hot (T K) phase of the Warm Hot Intergalactic Medium (WHIM). While the hot WHIM is hard to detect d…
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…
Tracing the cosmic web
Noam I Libeskind, Rien van de Weygaert, Marius Cautun +27
The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of dense regions packed fu…
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…
