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 …
This three-month work plan for the visiting professor Dr. Lopes de Oliveira at IAG / USP has the following main goals (i) to contribute for maximizing the scientific community's exploration potential of the astronomical observations conducted by the Southern Photometric Local Universe survey project (S-PLUS) by building a catalog of Halpha sources, and (ii) establishing a pilot project to…
This Projeto Regular is the continuation of three previous grants, which supported the construction and maintenance of SAM-FP and T80-South. SAM-FP installed inside the SOAR Adaptive Module (SAM), at the SOAR telescope, is functional and can be used to obtain data cubes with spectral resolution of 11200 and spatial resolution of 0.5 arcsec (with ground-layer adaptive optics correction). W…
The advent of two new instruments SAM-FP on the SOAR telescope and T80-South gives us a unique chance now to explore a number of studies of nearby galaxy structure, chemical enrichment, formation and evolution. The overall goal that both instruments allow is the study of evolution processes of star formation in disks of nearby galaxies, including our own Galaxy, in environments of differe…

Multi-band surveys such as the Southern photometric Local Universe survey (Mendes de Oliveira et al. 2019) have a key advantage: the narrow band that covers the magnesium triplet (filter J0515) is sensitive to the surface gravity of stars, which allows the selection of distant giant stars (e.g. Majewski et al., 2000). Cleaning the sample of nearby dwarf stars is crucial, as they can corre…

The main goals of this research project consist of training and evaluating predictive models for redshifts of quasars using photometric data from the Southern Photometric Local Universe Survey (S-PLUS) in a supervised machine learning context. S-PLUS data from quasars previously confirmed via spectroscopy by the Sloan Digital Sky Survey (SDSS) will be used for model training. In this proj…
One recent discovery has challenged our theoretical understanding of the life histories of galaxies. Ultra Diffuse Galaxies (UDGs) were found unexpectedly in extremely deep images of clusters of galaxies. Intriguingly, these are galaxies that have the sizes of giants but the luminosities of dwarfs.In this project, we will address problems in galaxy formation and evolution using observatio…

Several new instruments have been or are being built with the main goal of identifying potentially hazardous inner solar bodies. The main examples are Pan-STARRS and LSST - the latter will enhance the number of known small bodies by at least one order of magnitude. S-PLUS, the first Brazilian-led survey of the southern sky, in 12 bands, funded mostly by FAPESP, can also give an effective …
In this application we describe two projects for an 1-year BEPE at the University of Washington under Prof. Dr. Zeljko Ivezic's supervision. The first project is an on-going work on quasar photometric redshift estimation using a supervised learning approach and S-PLUS data. With the improved precision of our estimation technique, we will be able to build a quasar candidate catalogue for f…
During the BEPE fellowship, I will work on three different projects that are related to each other. The first 2 (Projects A and B) are already in an advanced stage of development, while the last one (Project C) will be started during the BEPE. In Project A, we take advantage of the S-PLUS narrow band filters to select giant stars in specific color-color diagrams. These giant stars will be…
