The proposed visit aims to advance studies of galaxies within the framework of the Southern Photometric Local Universe Survey (S-PLUS, www.splus.iag.usp.br), an international collaboration led by Dr. C. Mendes de Oliveira (IAG-USP). S-PLUS employs an innovative system of 12 photometric filters - the conventional ugriz bands plus seven narrow bands (~100 Å) - to map over 9000 square degree…
This thematic grant application is the natural continuation of a previous successful project funded by FAPESP to build a 0.8m-aperture optical robotic telescope+wide camera, and implement an optical survey over a large area of the southern sky. The telescope, T80-South, and its large-format camera were mounted and successfully comissioned at Cerro Tololo, Chile, and they are now in regul…
Astronomy in the 21st century continues to be a vibrant science; the more so as each decade passes. With the new generation of telescopes that is being currently planned, it will be possible to look for habitable Earth-like planets; to the inner regions of circumstellar disks, revealing the mechanisms that drive planetary and stellar formation; to resolve dense stellar populations in the …
We plan to use {\it machine learning} and {\it deep learning} tools in the analysis of large photometric and spectroscopic surveys, such as S-PLUS, J-PLUS, J-PAS and PFS, to extract the information contained in the large datasets that are or will be generated by these projects. Our initial focus is the analysis of the data that S-PLUS has been obtaining, but the techniques will be applied…
This intensive 10-day school will introduce the future generation of young astronomers to the forefront of the theoretical and observational developments of the astrophysics of the epoch of re-ionisation. The school is centred around 8 main lecture courses delivered by top international experts in this field that will cover the cosmic dark ages, the formation of the first stars, galaxies …
PFS, the Prime Focus Spectrograph, will be a spectrograph with 2394 fibers, mounted on the 8m Subaru telescope, and is being built by an international consortium. Brazil is responsible for building the optical fiber sub-system of this instrument, called FOCCOS, which is being done by a partnership involving IAG and LNA / MCTIC, with the support of several technology-based companies in São…

Este projeto visa desenvolver uma prova de conceito para a interface entre o Sistema de Controle do Observatório (OCS) do Telescópio Gigante de Magalhães (GMT) e o instrumento de Óptica Adaptativa Extrema do GMT (GMagAO-X). O Sistema de Controle de Dispositivo (DCS) será desenvolvida seguindo a arquitetura e procedimentos criados pela equipe de Software e Controle do GMT, que desenvolve e…
O objetivo deste projeto é desenvolver ferramentas para o estudo de galáxias barradas e galáxias jellyfish. Nossos objetivos são descritos a seguir:* Quantificar como barras estelares, bojos e braços espirais influenciam a atividade de formação estelar e a morfologia das galáxias.* Determinar o papel do chamado ram-pressure stripping e outros fatores ambientais na modulação do impacto das…
Quasars are powerful tracers of the Cosmic Web, revealing an evolutionary trend in which their spatial distribution shifts from dense environments at cosmic noon to lower-density regions in the nearby Universe. This project aims to investigate underexplored correlations between quasar properties (e.g., luminosity, spectra, color) and their positions within Large-Scale Structure (LSS) comp…

Studying the stellar populations of galaxies provides valuable information about theirformation, evolution and structure. By analyzing the spectral characteristics of galaxies,we can extract important information about the ages, metallicities and star formationhistories of their stellar populations. In this project we will develop a tool to simulate thephotometry of multiband surveys, suc…
O GMACS, um dos mais importantes instrumentos do telescópio GMT - Giant Magellan Telescope, é um espectrógrafo de múltiplos objetos no visível, de dispersão moderada, com canais vermelho e azul. Ele está projetado para operar com visão natural, mas sua sensibilidade será aprimorada com a correção de óptica adaptativa.O grupo brasileiro (GMTBrO) vem atuando fortemente e, com grande protago…
O projeto GMT-FAPESP criou um grupo de divulgação científica para compartilhar as iniciativas desenvolvidas pelo projeto para a sociedade brasileira. Desde novembro de 2020, conteúdo audiovisual a respeito do Telescópio Gigante Magalhães (GMT) e as áreas de pesquisa que ele poderá contribuir estão sendo compartilhados nas redes sociais oficiais (Facebook, Instagram, Twitter e Youtube). As…

We plan to perform systematic searches in the Hyper Suprime-Cam – Subaru Strategic Program (HSC-SSP) data for clusters and protoclusters of galaxies at 0< z r 2. Our strategy consists of extensive use of realistic mock data to validate selection criteria and tuning probabilistic model parameters in order to calculate the probability of a given galaxy being the cluster's dominant one (BCG)…
The main objective of this project is to constrain the Galactic (especially the dark matter halo) potential making use of accurate 3 dimensional positions and velocities (phase space coordinates) of millions of stars in the stellar halo provided by the Gaia survey and a ground based spectroscopic survey (DESI). The availability of accurate phase space coordinates can yield orbits for thes…
This project aims to identify galaxy clusters in the Kilo-Degree Survey (KiDS) databaseand to investigate how galaxies evolve in clusters at different scales and environments.This survey data consists of observations in 9 photometric bands (optical and near-infrared) and estimated photometric redshifts. A magnitude-limited galaxy sample will beextracted from the KiDS database. Initially, …
