In the last years priority was given to equipments for informatics, and in the last RTI priority was given to the acquisition of 2 cars for field work particularly important for geophysics, and maintenance and change of pieces of the Estação Meteorológica. In this RTI we are demanding itens of equipaments for laboratories, and other itens described below: The total amount of the RTI-Fapes…
The project aims at the participation on the design, construction and scientific use of the MOSAIC spectrograph, to be installed at the Extremely Large Telescope (ELT), the largest optical telescope ever planned, with a mirror of 39m in diameter, being installed in Chile. The excellent quality and future impact in the brazilian astronomical instrumentation and science is at a low cost as …
Summary: The total value of the R.T.I. -FAPESP is BRL 742,375.55. In years prior to R.T.I. <ç<÷FAPESP destined for the IAG was essentially used to provide the Institute with a Center forData Processing (CPD) compatible with your research needs. For such,the CPD of the Department of Astronomy was reformed, which became the Data Centerof IAG, enabling it to absorb new clusters and the more …
O VII Encontro VISCACHA é a reunião internacional anual da colaboração VISCACHA (VIsibleSoar photometry of star Clusters in tApii and Coxi HuguA), onde são apresentados novos resultados científicos,discutidas novas idéias, e desenvolvidos projetos, além de acolher novos membros. É uma reunião aberta aopúblico acadêmico visando crescer a colaboração, em particular no Estado de São Paulo, …
The Galactic bulge is the most complex region of the Milky Way. Over the past 20 years, we have been analyzing various samples, focusing par ticularly on stellar chemical abundances and kinematical properties. For a comprehensive analysis of these samples, an important new element is to complementour results with the proper motion data from the Gaia mission, computing precise distances wi…
Cars for fieldwork and repair of equipments:The itens requested include two Pick-up for fieldwork and funds for maintenance of the da meteorological Tower of IAG.Two Pick-up are needed for fieldwork in Applied Geophysics, in their studies of exploration of mineral resources. Some examples are: silting of rivers and lakes in the Pantanal basin at Mato Grosso (Coxim-MT); studies of arqueol…

The next generation of 30-meter class telescopes, exemplified by ESO's Extremely Large Telescope (ELT), imposes unprecedented structural stability and pointing precision requirements on ground-based astronomy. MOSAIC, the ELT's flagship multi-object spectrograph, faces critical engineering challenges regarding its Instrument Core Structure (ICOS), consisting of a static metal structure an…
The Galactic bulge is the most complex component of the Milky Way, containing stars from the spheroidal bulge, but also from the inner thin andthick disks, halo, stars formed later in the bar, and from accreted objects. The aim of this work is to analyse the old spheroidal bulge.During the early Galaxy formation, the dense gas led to formation of massive stars, that exploded as supernovae…
O bolsista será responsável pela modelagem e simulação de um robô SCARA de dois graus de liberdade e pela prototipagem da placa de controle (hardware e software) do posicionador em primeiro lugar e, posteriormente, pelo controle do subsistema central do instrumento (ICOS) do instrumento MOSAIC. O posicionador é uma parte do instrumento MOSAIC responsável por captar a luz do plano focal do…

The Galactic bulge is the most complex region of the Galaxy, because it was the first structure to be formed, but after that other stellar populations occupy this region such as the thin and thick disksand halo, besides the formation of the bar that caused transfer of gas and stars from the disk to the inner Galaxy. Moreover, accretion of dwarf galaxies took place, of which stellar popula…
A fundamental aspect of advances in astrophysics relies on the quality and precision of data collected by high-performance instruments, such as the multi-object spectrograph MOSAIC (Multi-Object Spectrograph for Astrophysics, Inter-galacticmedium studies and Cosmology), designed for the Extremely Large Telescope (ELT) - the largest telescope in the world operating in the optical/near-infr…
Chemical abundances in the Galactic bulge are key to understandthe early enrichment from massive supernovae. In particular in the Galactic bulge, the gas was dense and star formation and explosion of the first supernovae caused a fast chemical enrichment. We have a sample of bulge starsobserved at high-resolution spectroscopy with the Very Large Telescope at the European Southern Observat…

Active galactic nuclei (AGNs) occur when a supermassive black hole (SMBH) accretes matter in a considerable rate. Therefore, such objects need the feeding of matter in order to become active. Studies show that there are correlations between the central SMBH and some parameters of their host galaxies, what suggest a co-evolution between galaxies and their central SMBHs. The feeding mechani…
Foram obtidas 4 noites de observação com o Very Large Telescope - Eso para espectroscopia de alta resolução, para 2 programas: (1) estrelas de aglomerados globulares do bojo; (2) estrelas de campo do bojo. Em ambos os casos o objetivo é realizar análise detalhada para determinação da metalicidade (FE/H) e razões de abundâncias de elementos -, elementos - S e R. Estes resultados podem impo…
Foram obtidas 1) 5 noites no telescópio de 1.5 m, para espectroscopia a média resolução no infravermelho próximo, de galáxias elípticas, e 2) 3 noites no telescópio de 1.4 m para observação a alta resolução de estrelas gigantes ricas em Lítio. (AU)
