Abstract

The goal of this grant proposal (Auxílio a 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 modeling of groups, clusters and superclusters, using techniques developed and/or used by our team, we hope to gain a precise understanding of the aspects of dynamic evolution and the relationship between baryonic matter and dark matter in these large structures. This project is associated with the J-PAS and S-PLUS surveys, with strong participation of IAG/USP colleagues. (AU)
