S-PLUS Clusters And Large-scale Environments (SCALE): I. A catalog of known clusters and groups in DR5 and a pilot study of Abell 4038
C. Mendes de Oliveira, N. M. Cardoso, P. A. A. Lopes +26
Within the framework of the Southern Photometric Local Universe Survey (S-PLUS), we introduce -PLUS lusters nd arge-scale nvironments (…
The Limits of Photometric Dynamics: Benchmarking Cluster Relaxation Diagnostics
Alisson P. Costa, Andre L. B. Ribeiro, Zhonglue L. Wen +1
Galaxy clusters are key probes of cosmology and structure formation, yet their dynamical classification traditionally relies on spectroscopic redshifts, which do not scale efficien…
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…
The Kormendy relation of cluster galaxies in PPS regions
André L. B. Ribeiro, Paulo A. A. Lopes, Dailer F. Morell +4
We study a sample of 936 early-type galaxies located in 48 low-z regular galaxy clusters with at . We examine variations in the Kormendy rela…
The Role of Groups in Galaxy Evolution: compelling evidence of pre-processing out to the turnaround radius of clusters
P. A. A. Lopes, A. L. B. Ribeiro, D. Brambila
We present clear and direct evidence of the pre-processing effect of group galaxies falling into clusters in the local Universe (). We start with a sample of 238 cl…
Late growth of early-type galaxies in low-z massive clusters
A. L. B. Ribeiro, R. S. Nascimento, D. F. Morell +3
We study a sample of 936 early-type galaxies (ETGs) located in 48 low-z regular galaxy clusters with at . We examine variations in the concen…
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…
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
