Star-formation efficiency and metal enrichment of the intracluster medium in local massive clusters of galaxies
We have investigated the baryon-mass content in a subsample of 19 clusters of galaxies extracted from the X-ray flux-limited sample HIFLUGCS according to their positions in the sky. For these…
On the influence of non-thermal pressure on the mass determination of galaxy clusters
Aims. Given that in most cases just thermal pressure is taken into account in the hydrostatic equilibrium equation to estimate galaxy cluster mass, the main purpose of this paper is to consider the…
Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376
The galaxy cluster Abell~3376 is a nearby (z=0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger system is comprised of…
Optical substructure and BCG offsets of Sunyaev-Zel'dovich and X-ray-selected galaxy clusters
We used optical imaging and spectroscopic data to derive substructure estimates for local Universe ($z < 0.11$) galaxy clusters from two different samples. The first was selected through the…
Physical properties of the X-ray gas as a dynamical diagnosis for galaxy clusters
We analysed XMM-{\it Newton} EPIC data for 53 galaxy clusters. Through 2D spectral maps, we provide the most detailed and extended view of the spatial distribution of temperature (kT), pressure (P),…
The clusters Abell 222 and Abell 223: a multi-wavelength view
Context. The Abell 222 and 223 clusters are located at an average redshift z ∼ 0.21 and are separated by 0.26 deg. Signatures of mergers have been previously found in these clusters, both in X-rays…
A NEW METHOD TO QUANTIFY X-RAY SUBSTRUCTURES IN CLUSTERS OF GALAXIES
We present a new method to quantify substructures in clusters of galaxies, based on the analysis of the intensity of structures. This analysis is done in a residual image that is the result of the…
A metal-rich elongated structure in the core of the group NGC 4325
We used X-ray 2D spectrally resolved maps to resolve structure in temperature and metal abundance. To perform stellar population analysis we applied the spectral fitting technique with STARLIGHT to…
Testing stellar population fitting ingredients with Globular Clusters I: Stellar libraries
The integrated spectra of stellar systems contain a wealth of information, and its analysis can reveal fundamental parameters such as metallicity, age and star formation history. Widely used methods…
Substructure analysis of the RXCJ0232.2–4420 galaxy cluster
RXCJ0232.2-4420, at z = 0.28, is a peculiar system hosting a radio halo source around the cool-core of the cluster. To investigate its formation and nature, we used archival Chandra and XMM-Newton…
