Satellite galaxies in nearby groups of galaxies

Autor: Vennik, J., Hopp, U.

We analyse distribution, kinematics and star-formation (SF) properties of satellite galaxies in three different samples of nearby groups. We find that studied groups are generally well approximated by low-concentration NFW model, show a variety of LO

Multimodality of rich clusters from the SDSS DR8 within the supercluster-void network

Autor: Einasto, M., Liivamagi, L. J., Tempel, E., Saar, E., Vennik, J., Nurmi, P., Gramann, M., Einasto, J., Tago, E., Heinamaki, P., Ahvensalmi, A., Martinez, V. J.

We study the relations between the multimodality of galaxy clusters drawn from the SDSS DR8 and the environment where they reside. As cluster environment we consider the global luminosity density field, supercluster membership, and supercluster morph

Testing of the dwarf galaxy content and the evolutionary status of nearby groups of galaxies

Autor: Vennik, J., Hopp, U.

We carried out visual and parametric searches for dwarf galaxies in five loose groups of galaxies. Follow-up spectroscopy with the HET has shown a 50% success rate of morphological selection. The evolutionary status of the studied groups differs: whi

Groups of galaxies in the SDSS Data Release 5. A group-finder and a catalogue

Publikováno v: Astron.Astrophys.479:927-937,2008

We extract groups of galaxies from the SDSS Data Release 5 with the purpose of studying the supercluster-void network and environmental properties of groups therein. We use a modified friends-of-friends (FoF) method with adopted variable linking leng
