The Shape of Velocity Dispersion Profiles and the Dynamical State of Galaxy Clusters
A. P. Costa, A. L. B. Ribeiro, R. R. de Carvalho
Motivated by the existence of the relationship between the dynamical state of clusters and the shape of the velocity dispersion profiles (VDP), we study the VDPs for Gaussian (G) a…
The NGC 454 system: anatomy of a mixed on-going merger
H. Plana, R. Rampazzo, P. Mazzei +3
This paper focuses on NGC 454, a nearby interacting pair of galaxies (AM0112-554, RR23), composed of an early-type (NGC 454 E) and a star forming late-type companion (NGC 454 W). W…
Investigating the Relation between Galaxy Properties and the Gaussianity of the Velocity Distribution of Groups and Clusters
R. R. de Carvalho, A. L. B. Ribeiro, D. Stalder +3
We investigate the dependence of stellar population properties of galaxies on group dynamical stage for a subsample of Yang catalog. We classify groups according to their galaxy ve…
