Internal kinematics of spiral galaxies in distant clusters III. Velocity fields from FORS2/MXU spectroscopy
E. Kutdemir, B. L. Ziegler, R. F. Peletier +8
(Abridged) We study the impact of cluster environment on the evolution of spiral galaxies by examining their structure and kinematics. Rather than two-dimensional rotation curves,…
Intragroup diffuse light in compact groups of galaxies II. HCG 15, 35 and 51
C. Da Rocha, B. L. Ziegler, C. Mendes de Oliveira
This continuing study of intragroup light in compact groups of galaxies aims to establish new constraints to models of formation and evolution of galaxy groups, specially of compac…
Intra-group Light in Hickson Compact Groups
Cristiano Da Rocha, Claudia Mendes de Oliveira, Bodo L. Ziegler
We have analyzed the intra-group light component of 3 Hickson Compact Groups (HCG 79, HCG 88 and HCG 95) with detections in two of them: HCG 79, with of the total ba…
Intra-Group Light in Hickson Compact Groups - A Wavelet Approach
Cristiano Da Rocha, Claudia Mendes de Oliveira, Bodo L. Ziegler
A diffuse component of intra-group light can be observed in compact groups of galaxies. This component is presumably due to stellar material tidally stripped from the member galaxi…
Optical Diffuse Light in Nearby Compact Groups
C. Mendes de Oliveira, C. Da Rocha, C. R. Rabaça +2
Analyses of B and R band observations of four compact groups reveal the presence of a considerable amount of diffuse, intergalactic light in two of them (HCG 79 and HCG 95). The di…
Globular Clusters in Compact Groups
C. Da Rocha, C. Mendes de Oliveira, M. Bolte +2
We have studied globular cluster systems (GCSs) around elliptical galaxies in Hickson compact groups using multi-band deep, high quality images from Keck, VLT and CFHT. Analyzing t…
