The evolution of 3C 306 in the galaxy cluster RXCJ1454.4+1622: linking spectral ageing, ICM conditions, and jet dynamics through MHD simulations
A. S. R. Antas, A. Caproni, L. Loinard +2
We present a methodology for analysing radio sources in galaxy clusters by combining multi-frequency radio observations, X-ray analysis of the intracluster medium (ICM), and three-…
Simulating nearly edge-on sloshing in the galaxy cluster Abell 2199
Rubens E. G. Machado, Tatiana F. Laganá, Gilvan S. Souza +3
Off-axis collisions between galaxy clusters may induce the phenomenon of sloshing, causing dense gas to be dragged from the cool core of a cluster, resulting in a spiral of enhance…
Substructure analysis of the RXCJ0232.2-4420 galaxy cluster
Viral Parekh, Tatiana F. Laganá, Ruta Kale
RXCJ0232.2-4420, at = 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 {\it…
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…
The dynamical state of Abell 2399: a bullet-like cluster
Ana C. C. Lourenço, P. A. A. Lopes, T. F. Laganá +8
While there are many ways to identify substructures in galaxy clusters using different wavelengths, each technique has its own caveat. In this paper, we conduct a detailed substruc…
NGC 4104: a shell galaxy in a forming fossil group
G. B. Lima Neto, F. Durret, T. F. Laganá +4
Groups are the most common association of galaxies in the Universe, found in different configuration states such as loose, compact and fossil groups. We have studied the galaxy gro…
Simulations of gas sloshing induced by a newly discovered gas poor substructure in galaxy cluster Abell 1644
L. Doubrawa, R. E. G. Machado, T. F. Laganá +3
Collision events lead to peculiar morphologies in the intracluster gas of galaxies clusters. That seems to be the case of Abell 1644, a nearby galaxy cluster, composed of three mai…
A rare case of FR I interaction with a hot X-ray bridge in the A2384 galaxy cluster
V. Parekh, T. F. Laganá, K. Thorat +3
Clusters of varying mass ratios can merge and the process significantly disturbs the cluster environments and alters their global properties. Active radio galaxies are another phen…
Two merging galaxy clusters with very hot shock fronts observed shortly before pericentric passage
T. F. Laganá, G. S. Souza, R. E. G. Machado +2
We present a detailed analysis of two merging clusters, from XMM-\textit{Newton} X-ray archival data: PLCKESZ G036.7+14.9 (; hereafter G036) and PLCK G292.5+22.0 (;…
Testing Stellar Population Fitting Ingredients with Globular Clusters I: Stellar Libraries
Lucimara P. Martins, Círia Lima-Dias, Paula R. T. Coelho +1
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. W…
Optical Substructure and BCG Offsets of Sunyaev-Zel'dovich and X-ray Selected Galaxy Clusters
P. A. A. Lopes, M. Trevisan, T. F. Laganá +3
We used optical imaging and spectroscopic data to derive substructure estimates for local Universe () galaxy clusters from two different samples. The first was selected t…
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…
A metal-rich elongated structure in the core of the group NGC4325
T. F Laganá, L. Lovisari, L. Martins +3
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…
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…
A New Method to Quantify X-ray Substructures in Clusters of Galaxies
Felipe Andrade-Santos, Gastão B. Lima Neto, Tatiana F. Laganá
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 t…
Star-formation efficiency and metal enrichment of the intracluster medium in local massive clusters of galaxies
Yu-Ying Zhang, Tatiana F. Laganá, Daniele Pierini +3
