The goal of this grant proposal (\textit{Auxílio à Pesquisa}) is to provide the necessary subsidies for the continuation and development of the work carried out by my group at the Department of Astronomy, IAG/USP.Through panchromatic (mainly X-ray and optical) observations and numerical modelling of galaxies, groups, clusters and superclusters, using techniques developed and/or used by ou…

We aim at studying the chemical enrichment of the intergalactic medium in groups of galaxies designing a comparative programme between simulations and observations. This programme will provide insights on the process of chemical recycling between galaxies and in the medium they inhabit and will help to set constrains on galaxy formation models. Because of the complexity and non-linear gro…
Professor Melville Ulmer will spend two weeks at IAG/USP where he will give a series of lectures on astronomical satellites, focusing on X-ray astronomy. These lectures will be part of a mini-course offered by the Graduate Astronomy Program at IAG. During the first week we will focus on technical topics such as the design and development of satellites. In the second week of the course he …

The main goal of this work is to study and analyze collisions between galaxy groups and clusters using numerical simulations and observations in optical and X-rays. These collisions last for about several billion years and involve energies that can reach up to about $10^{64}$~Ergs. The study of these collisions reveals how the largest structures formed in the Universe. By constructing a s…
The main goal of this project is to study the properties of galaxies in cosmic filaments, looking for correlations between observable properties obtained through galaxy imaging and the density and structure of the environment. In this way, we seek to obtain information about how the evolution of galaxies is affected in these filaments. The regions that will be studied are in the neighborh…
The main goal of this work is the quantitative determination of the degree of substructures in nearby galaxy clusters (z < 0.02), observed in X-rays by the Chandra satellite. This study will be carried out systematically, using objective criteria to determine substructures observed in the surface brightness in the [0.5--8.0 keV] band. Within pre-defined regions, we will determine the rati…

In this "Scientific Initiation" work, the surface brightness of the brightest galaxies in groups and clusters will be studied, as well as the diffuse light from the intra-cluster/intra-group environment. The origin of the diffuse light, usually associated with the stellar envelope of the brightest galaxies, comes from the population of stars torn out from galaxies by tidal effects and, th…
The main goal of this undergraduate project is to study and analyse quantitatively the effects due to tidal forces and dynamical friction in galaxies member of groups and clusters. These effects impact directly galaxy evolution and contribute to the formation of giant galaxies in the center of clusters. Also, tidal forces feed the intracluster medium with stars, observable as a diffuse li…
Rich galaxy clusters are the last and largest collapsed structures in the Universe. These structures grow by successive mergers according to the hierarchical scenario as a consequence of matter being dominated by a non-collisional cold component. In the present IC project, we intend to analyze the physical properties of clusters in collision through the use of N-body simulations. Comparin…

Gravitational dynamical processes are essential for the formation and evolution of structures in the universe. When we have an object inserted into a given environment, several processes will act differently in determining their dynamical history. Here, we will focus on tidal forces and dynamical friction. The former will be responsible for mass loss and, in more extreme cases, will lead …
The mass and redshift distribution of galaxy clusters are key observables to determine the parameters of the cosmological model of the universe. The great challenge, however, is the efficient selection and precise determination of the masses of these objects. Samples selected based only on photometric data are subject to various complications such as projection effects, fragmentation due …
In this PhD project, we are trying to better explain how the environment of galaxy clusters affect the evolution of member galaxies, by means of hydrodynamic simulations. For this purpose, we have been using the state of the art, open source code RAMSES, originally developed by Romain Teyssier at CEA Saclay, France. In this BEPE internship project, we intend to enhance our current models …
