The Radial Acceleration Relation in Galaxies and Clusters from a Two-Component, Virial-Motivated Framework

Christine C. Dantas, Andre L. B. Ribeiro, Hugo V. Capelato

We present a comparative analysis of acceleration data for gravitational systems drawn from multiple observational sources, including: (i) early-type galaxies (ETGs) (Lelli et al.…

Examining transitional galaxies to understand the role of clusters and their dynamical status in galaxy quenching

Douglas Brambila, Paulo A. A. Lopes, André L. B. Ribeiro +1

In this work, we consider four different galaxy populations and two distinct global environments in the local Universe (z ) to investigate the evolution of transitional…

Investigating the Projected Phase Space of Gaussian and Non-Gaussian Clusters

V. M. Sampaio, R. R. de Carvalho, I. Ferreras +3

By way of the projected phase-space (PPS), we investigate the relation between galaxy properties and cluster environment in a subsample of groups from the Yang Catalog. The sample…

Probing Saraswati's heart: evaluating the dynamical state of the massive galaxy cluster A2631 through a comprehensive weak-lensing and dynamical analysis

R. Monteiro-Oliveira, A. C. Soja, A. L. B. Ribeiro +4

In this work, we investigate the dynamical state of the galaxy cluster Abell 2631, a massive structure located at the core of the Saraswati supercluster. To do this, we first solve…

Stellar Population Properties of ETGs in Compact Groups of Galaxies

Tatiana C. Moura, Reinaldo R. de Carvalho, Sandro B. Rembold +6

We present results on the study of the stellar population in Early-Type galaxies (ETGs) belonging to 151 Compact Groups (CGs). We also selected a field sample composed of 846 ETGs…

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…
