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…

In this project, we will study how the properties of the stellar populations of galaxies depend on the global parameters of the groups where they reside. For this, we will select groups of galaxies in the local universe ($z \simless 0.01$) and analyze the stellar populations of their members using spectral synthesis techniques applied to the S-PLUS photometry. This will allow us to assess…

We plan to perform systematic searches in the Hyper Suprime-Cam - SubaruStrategic 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 validateselection criteria and tuning probabilistic model parameters in order to calculatethe probability of a given galaxy being the cluster's dominant one (BCG) an…
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, …
Given the large amounts of data currently available in cosmology and its expected growth in the near future, optimal methods for analysing data are crucial. Galaxy surveys under building phase, including those in which Brazil is involved - the J-PAS and the PFS, for instance - will cover much larger volumes than current surveys and will reach cosmological scales neverprobed before. Althou…
