Diffuse light in the young cluster of galaxies CL J1449+0856 at z=2.07
C. Adami, F. Durret, L. Guennou +1
Cluster properties do not seem to be changing significantly during their mature evolution phase, for example they do not seem to show strong dynamical evolution at least up to z~0.…
Intracluster light in clusters of galaxies at redshifts 0.4<z<0.8
L. Guennou, C. Adami, C. Da Rocha +27
The study of intracluster light can help us to understand the mechanisms taking place in galaxy clusters, and to place constraints on the cluster formation history and physical pro…
Two formation channels of UCDs in Hickson Compact Groups
C. Da Rocha, S. Mieske, I. Y. Georgiev +3
The formation of ultra-compact dwarf galaxies (UCDs) is believed to be interaction driven, and UCDs are abundant in the cores of galaxy clusters, environments that mark the end-poi…
Internal kinematics of spiral galaxies in distant clusters IV. Gas kinematics of spiral galaxies in intermediate redshift clusters and in the field
Elif Kutdemir, Bodo Ziegler, Reynier Peletier +3
(Abridged) We trace the interaction processes of galaxies at intermediate redshift by measuring the irregularity of their ionized gas kinematics, and investigate these irregulariti…
Intra-group diffuse light in compact groups of galaxies. HCG 79, HCG 88 and HCG 95
Cristiano Da Rocha, Claudia Mendes de Oliveira
Deep and images of three Hickson Compact Groups, HCG 79, HCG 88 and HCG 95, were analyzed using a new wavelet technic to measure possible intra-group diffuse light present…
Globular Clusters around Galaxies in Groups
C. Da Rocha, C. Mendes de Oliveira, M. Bolte +2
We have obtained deep photometry of NGC 1199 (in HCG 22) and NGC 6868 (in the Telescopium group). Both galaxies are the optically brightest galaxies of their groups. Our analysis o…
