Integral Field Spectroscopy of Collisional Ring Galaxies I: Stellar Populations Analysis
M. Chow-Martínez, A. Robleto-Orús, Y. D. Mayya +9
Collisional ring galaxies are produced by the collision of a disk galaxy with a compact galaxy plunging through the disk, forming a ring-shaped expanding density wave, triggering s…
Nucleation regions in the Large-Scale Structure II: Morphology and dynamical state of supercluster cores
J. M. Zúñiga, C. A. Caretta, H. Andernach
This work explores the morphology and dynamical properties of cores within rich superclusters, highlighting their role as transitional structures in the large-scale structure of th…
Nucleation regions in the Large-Scale Structure I. A catalogue of cores in nearby rich superclusters
J. M. Zúñiga, C. A. Caretta, H. Andernach
We applied a Density-Based Clustering algorithm on samples of galaxies and galaxy systems belonging to 53 rich superclusters from the \textit{Main SuperCluster Catalogue} (MSCC) to…
Testing an entropy estimator related to the dynamical state of galaxy clusters
J. M. Zúniga, C. A. Caretta, A. P. González +1
We propose the entropy estimator , calculated from global dynamical parameters, in an attempt to capture the degree of evolution of galaxy systems. We assume that the observed…
Tracing the assembly histories of galaxy clusters in the nearby universe
César A. Caretta, Heinz Andernach, Marcel Chow-Martínez +10
We have compiled a sample of 67 nearby ( < 0.15) clusters of galaxies, for which on average more than 150 spectroscopic members are available, and, by applying different methods…
Environmental cluster effects and galaxy evolution: The HI properties of the Abell clusters A85/A496/A2670
M. M. López-Gutiérrez, H. Bravo-Alfaro, J. H. van Gorkom +6
We study the impact of local environment on the transformation of spiral galaxies in three nearby () Abell clusters: A85/A496/A2670. These systems were observed in HI wit…
