The dynamical state of Abell 2399: a bullet-like cluster
Ana C. C. Lourenço, P. A. A. Lopes, T. F. Laganá +8
While there are many ways to identify substructures in galaxy clusters using different wavelengths, each technique has its own caveat. In this paper, we conduct a detailed substruc…
Classification and Evolution of Galaxies According to the Dynamical State of Host Clusters and Galaxy Luminosities
D. F. Morell, A. L. B. Ribeiro, R. R. de Carvalho +3
We analyze the dependence of galaxy evolution on cluster dynamical state and galaxy luminosities for a sample of 146 galaxy clusters from the Yang SDSS catalog. Clusters were split…
The Mass Density Profile and Star Formation History of Gaussian and Non-Gaussian Clusters
R. R. de Carvalho, A. P. Costa, T. C. Moura +1
This paper is the third of a series in which we investigate the discrimination between Gaussian (G) and Non-Gaussian (NG) clusters, based on the velocity distribution of the member…
Optical Substructure and BCG Offsets of Sunyaev-Zel'dovich and X-ray Selected Galaxy Clusters
P. A. A. Lopes, M. Trevisan, T. F. Laganá +3
We used optical imaging and spectroscopic data to derive substructure estimates for local Universe () galaxy clusters from two different samples. The first was selected t…
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…
