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…
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…
The merger history of the complex cluster Abell 1758: a combined weak lensing and spectroscopic view
Rogério Monteiro-Oliveira, Eduardo S. Cypriano, Rubens E. G. Machado +4
We present a weak-lensing and dynamical study of the complex cluster Abell 1758 (A1758, z = 0.278) supported by hydrodynamical simulations. This cluster is composed of two main str…
Simulating the shocks in the dissociative galaxy cluster Abell 1758N
Rubens E. G. Machado, Rogério Monteiro-Oliveira, Gastão B. Lima Neto +1
Major mergers between massive clusters have a profound effect in the intracluster gas, which may be used as a probe of the dynamics of structure formation at the high end of the ma…
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…
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…
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…
Simulations of Barred Galaxies in Triaxial Dark Matter Haloes: The Effects of Gas
Rubens E. G. Machado, E. Athanassoula, S. A. Rodionov
The baryonic discs of galaxies are believed to alter the shapes of the dark matter haloes in which they reside. We perform a set of hydrodynamical N-body simulations of disc galaxi…
