Unveiling the Dynamics in Galaxy Clusters: The Hidden Role of Low-Luminosity Galaxies in Coma
Alisson P. Costa, Andre. L. B. Ribeiro, Flavio R. de M. Neto +1
In this work, we study the Coma cluster, one of the richest and most well-known systems at low redshifts, to explore the importance of low-flux objects in the identification of clu…
Boosting the evolutionary picture of Cl 0024+17 and MS 0451-03: A case study at intermediate-redshift
A. P. Costa, A. L. B. Ribeiro, R. R. de Carvalho +1
In this work we improve the dynamic-evolutionary framework of two massive clusters at intermediate redshifts: Cl 0024+17 at and MS 0451-03 at . The spectro…
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…
The Influence of the Dynamic State of Galaxy Clusters on Segregation Phenomena and Velocity Dispersion Profiles
Raquel S. Nascimento, Paulo A. A. Lopes, André L. B. Ribeiro +2
In this work we investigate the influence of the dynamic state of galaxy clusters on segregation effects and velocity dispersion profiles (VDPs) for a sample of 111 clusters extrac…
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…
