Simulating the arrival of the southern substructure in the galaxy cluster Abell 1758
Rubens E. G. Machado, Ricardo C. Volert, Richards P. Albuquerque +2
Abell 1758 (z~0.278) is a galaxy cluster composed of two structures: A1758N and A1758S, separated by ~2.2 Mpc. The northern cluster is itself a dissociative merging cluster that ha…
What drives the corpulence of galaxies? I. The formation of central compact dwarf galaxies in TNG50
Abhner P. De Almeida, Gary A. Mamon, Avishai Dekel +1
Nearby dwarf galaxies display a variety of effective radii (sizes) at a given stellar mass, suggesting different evolution scenarios according to their final "stellar" size. The TN…
The active CGCG 077-102 NED02 galaxy within the Abell 2063 galaxy cluster
C. Adami, K. Parra Ramos, J. T. Harry +3
Within the framework of investigating the link between central super massive black holes in the core of galaxies and the galaxies themselves, we detected a variable X-ray source in…
Galaxy cluster mergers as triggers for the formation of jellyfish galaxies: case study of the A901/2 system
Rafael Ruggiero, Rubens E. G. Machado, Fernanda V. Roman-Oliveira +4
The A901/2 system is a rare case of galaxy cluster interaction, in which two galaxy clusters and two smaller groups are seen in route of collision with each other simultaneously. W…
The fate of the gaseous disks of galaxies that fall into clusters
Rafael Ruggiero, Gastão B. Lima Neto
Galaxy clusters are known to induce gas loss in infalling galaxies due to the ram pressure exerted by the intracluster medium over their gas content. In this paper, we investigate…
Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376
Rogério Monteiro-Oliveira, Gastão B. Lima Neto, Eduardo S. Cypriano +5
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 sys…
Galaxy clusters as probes for cosmology and dark matter
Elia S. Battistelli, Carlo Burigana, Paolo de Bernardis +8
In recent years, significant progress has been made in building new galaxy clusters samples, at low and high redshifts, from wide-area surveys, particularly exploiting the Sunyaev-…
Structure and dynamics of the supercluster of galaxies SC0028-0005
Ana Laura O'Mill, Dominique Proust, Hugo V C. apelato +4
According to the standard cosmological scenario, superclusters are objects that have just passed the turn around point and are collapsing. The dynamics of very few superclusters ha…
Two spectroscopically confirmed galaxy structures at z=0.61 and 0.74 in the CFHTLS Deep~3 field
C. Adami, E. S. Cypriano, F. Durret +6
Adami et al. (2010) have detected several cluster candidates at z>0.5 as part of a systematic search for clusters in the Canada France Hawaii Telescope Legacy Survey, based on phot…
Simulations of gas sloshing in galaxy cluster Abell 2052
Rubens E. G. Machado, Gastão B. Lima Neto
The intracluster plasma of Abell 2052 exhibits in X-rays a spiral structure extending more than 250 kpc, which is comprised of cool gas. This feature is understood to be the result…
Non-virialised clusters for detection of Dark Energy-Dark Matter interaction
Morgan Le Delliou, Rafael J. F. Marcondes, Gastao B. Lima Neto +1
The observation of galaxy and gas distributions, as well as cosmological simulations in a CDM Universe, suggests that clusters of galaxies are still accreting mass and are not e…
Structure in galaxy clusters
Gastao B. Lima Neto, Tatiana F. Lagana, Felipe Andrade-Santos +1
We will discuss here how structures observed in clusters of galaxies can provide us insight on the formation and evolution of these objects. We will focus primarily on X-ray observ…
The red sequence of Abell X-ray underluminous clusters
J. J. Trejo-Alonso, C. A. Caretta, T. F. Laganá +4
We present an analysis of the colour-magnitude relation for a sample of 56 X-ray underluminous Abell clusters, aiming to unveil properties that may elucidate the evolutionary stage…
The mass profile and dynamical status of the z~0.8 galaxy cluster LCDCS 0504
L. Guennou, A. Biviano, C. Adami +34
Constraints on the mass distribution in high-redshift clusters of galaxies are not currently very strong. We aim to constrain the mass profile, M(r), and dynamical status of the $z…
Structure and substructure analysis of DAFT/FADA galaxy clusters in the [0.4-0.9] redshift range
L. Guennou, C. Adami, F. Durret +29
We analyse the structures of all the clusters in the DAFT/FADA survey for which XMM-Newton and/or a sufficient number of galaxy redshifts in the cluster range is available, with th…
The merging cluster of galaxies Abell 3376: an optical view
Florence Durret, Clement Perrot, Gastao B. Lima Neto +3
Abell 3376 is a merging cluster of galaxies at redshift z=0.046, famous mostly for its giant radio arcs, and shows an elongated and highly substructured X-ray emission, but has not…
A comprehensive picture of baryons in groups and clusters of galaxies
T. F. Lagana, N. Martinet, F. Durret +3
(Abridged) Based on XMM-Newton, Chandra and SDSS data, we investigate the baryon distribution in groups and clusters and its use as a cosmological constraint. For this, we consider…
Simulations of the merging galaxy cluster Abell 3376
Rubens E. G. Machado, Gastão B. Lima Neto
Observed galaxy clusters often exhibit X-ray morphologies suggestive of recent interaction with an infalling subcluster. Abell 3376 is a nearby (z=0.046) massive galaxy cluster who…
Simulations of galaxy cluster mergers: the dynamics of Abell 3376
Rubens E. G. Machado, Gastão B. Lima Neto
In large scale structure formation, massive systems assemble through the hierarchical merging of less massive ones. Galaxy clusters, being the most massive and thus the most recent…
