New measurements of radial velocities in clusters of galaxies-V
(EDP SCIENCES S A, 2010)
As a part of our galaxy-cluster redshift survey, we present a set of 79 new velocities in the 4 clusters Abell 376, Abell 970, Abell 1356, and Abell 2244, obtained at Haute-Provence observatory. This set now completes our ...
The evolution of galaxies in compact groups
(Univ Chicago PressChicagoEUA, 1998)
Spiral-like structure at the centre of nearby clusters of galaxies
(EDP SCIENCES S A, 2010)
Context. X-ray data analysis have found that fairly complex structures at cluster centres are more common than expected. Many of these structures have similar morphologies, which exhibit spiral-like substructure. Aims. It ...
Large-scale study of the NGC 1399 globular cluster system in Fornax
(EDP Sciences, 2006-06)
We present a Washington C and Kron-Cousins R photometric study of the globular cluster system of NGC 1399, the central galaxy of the Fornax cluster. A large areal coverage of 1 square degree around NGC 1399 is achieved ...
FINDING FOSSIL GROUPS: OPTICAL IDENTIFICATION AND X-RAY CONFIRMATION
(IOP PUBLISHING LTDBRISTOL, 2012)
We report the discovery of 12 new fossil groups (FGs) of galaxies, systems dominated by a single giant elliptical galaxy and cluster-scale gravitational potential, but lacking the population of bright galaxies typically ...
Cluster and cluster galaxy evolution history from IR to X-ray observations of the young cluster RX J1257.2+4738 at z=0.866
(EDP SCIENCES S A, 2009)
Context. The cosmic time around the z similar to 1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge of the properties of ...
Reconstructing orbits of galaxies in extreme regions (ROGER) - II: Reliability of projected phase-space in our understanding of galaxy populations
(2022-02-01)
We connect galaxy properties with their orbital classification by analysing a sample of galaxies with stellar mass M⋆ ≥ 108.5h-1M⊙ residing in and around massive and isolated galaxy clusters with mass M200 > 1015h-1M⊙ at ...
Star formation activity and gas stripping in the Cluster Projected Phase-Space (CPPS)
(Oxford University PressOxford, 2014)
This work is focused on the study of the distribution in the Cluster Projected Phase-Space
(CPPS) of passive(ly-evolving) and star-forming galaxy populations and also, the intense and
quiescent star-forming populations ...
Galaxy properties in clusters: II. Backsplash galaxies
(EDP Sciences, 2014-04)
Aims: We explore the properties of galaxies on the outskirts of clusters and their dependence on recent dynamical history in order to understand the real impact that the cluster core has on the evolution of galaxies. ...
ROGER: Reconstructing orbits of galaxies in extreme regions using machine learning techniques
(Oxford Univ Press, 2021-01-01)
We present the ROGER (Reconstructing Orbits of Galaxies in Extreme Regions) code, which uses three different machine learning techniques to classify galaxies in, and around, clusters, according to their projected phase-space ...
