AXES-SDSS: comparison of SDSS galaxy groups with all-sky X-ray extended sources
S. Damsted, A. Finoguenov, H. Lietzen +8
We revisit the picture of X-ray emission of groups through the study of systematic differences in the optical properties of groups with and without X-ray emission and study the eff…
Properties of brightest group galaxies in cosmic web filaments
Teet Kuutma, Anup Poudel, Maret Einasto +4
Context. The cosmic web, a complex network of galaxy groups and clusters connected by filaments, is a dynamical environment in which galaxies form and evolve. However, the impact o…
Optical validation and characterization of Planck PSZ2 sources at the Canary Islands observatories. II. Second year of LP15 observations
A. Aguado-Barahona, R. Barrena, A. Streblyanska +4
We present the second and last year of observations of our optical follow-up programme 128-MULTIPLE-16/15B (LP15 )at Roque de los Muchachos Observatory (La Palma), which has been d…
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…
Large-scale environments of narrow-line Seyfert 1 galaxies
Emilia Järvelä, Anne Lähteenmäki, Heidi Lietzen +3
Studying large-scale environments of narrow-line Seyfert 1 (NLS1) galaxies gives a new perspective on their properties, particularly their radio loudness. The large-scale environme…
The effect of cosmic web filaments on the properties of groups and their central galaxies
Anup Poudel, Pekka Heinämäki, Elmo Tempel +3
The nature versus nurture scenario in galaxy and group evolution is a long-standing problem not yet fully understood on cosmological scales. We study the properties of groups and t…
