Cosmological applications of galaxy surveys depend on the proper identification of sources and extraction of the redshifts of extragalactic objects. This can be greatly enhanced by combining data from narrow-band surveys such as S-PLUS, J-PAS and J-PLUS with the deep photometry, superior spatial resolution and time domain capabilities of the Vera Rubin LSST.We will employ Machine Learning…
WEAVE-QSO and J-PAS are two large astrophysical surveys active from 2022 to 2029, on two major observatories, supported by two international collaborations: WEAVE-QSO (European) and J-PAS (mainly Brazilian-Spanish). These two surveys are partners towards a common goal: cosmology and galaxy formation in the first half of the history of the universe using data of unprecedented quality and s…
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…
The main goal of the present generation of extragalactic surveys (e.g., eBOSS and DES) is the exploration of cosmological parameters, in particular the equation of state of dark energy. However, there is now an increasing realization of the subtle interplay between between cosmology, large-scale structure, and galaxy evolution. Issues such as the bias of galaxies and halos, the pattern of…

Photometric surveys are quite complete (the number of galaxies can reach ~10^{-2} h^3 Mpc^{-3}), but the quality of photometric redshifts implies, in practice, a complex selection of galaxy populations that can effectively be used by these surveys. In order to study the completeness of these surveys, it is useful to compare them to others, deeper and/or spectroscopic. In 2024 we had the r…
Dark matter makes up about 85% of the universe's matter density. However, its fundamental nature is still unknown, representing a major gap in our understanding of the universe. There are many models for this elusive component. Ultra-light dark matter (ULDM), or ultra-light axions (ULA), are the lightest dark matter candidates, and, given their well-motivated microphysics and rich phenome…
With the new generation of massive astronomical experiments, analyzing the observations will require new and efficient computational techniques. The candidate's main research interests lie in large-scale structure and computational methods in cosmology. During his Ph.D., he acquired expertise in several sopisticated computational tools, especially using Machine Learning techniques, applie…

This project is aimed at an outstanding undergraduate student in Physics, Astronomy or the elite Molecular Sciences program at USP. In the first 6 months we will concentrate on the basic formation in General Relativity, Cosmology and notions about Cosmology, using standard textbooks [e.g., S. Carroll; B. Ryden; S. Dodelson; Mo, van den Bosch & White]. In the second part of the project (6 …
The $H_0$ problem is the present tension between local (direct) measurementes of the Hubble-Lemaître parameter, and high-redshift (indirect) measurements.The so-called ``$H_0$ tension'' is becoming one of the main challenges (perhaps even an embarassment) of modern cosmology.In this Scientific Initiation project the student will first get started on the basics of Relativistic Cosmology.Af…
Structure formation is one of the pillars of modern cosmology. The main tool for the study of the large-scale structures (LSS) of the Universe is the two-point function, which takes the form of the correlation function in real (configuration) space, or the power spectrum in Fourier space.One of the most fundamental tests of our cosmological models comes from comparing the theoretically co…

The new era of cosmological observations is generating huge amounts of data and increasing the pressure for improvements of both existing and new techniques to analyze those data. Machine learning (ML) methods are presently on the cutting-edge in terms of new techniques and tools, often surpassing traditional methods. However, in order to train ML algorithms a huge amount data is necessar…
The J-PAS survey of quasars and AGNs has the potential to become the largest, most complete survey of its kind, due to its narrow-band photometric system that can resolve the broad emission lines of quasars. With this BEPE project we will test our techniques (an optimized photo-z code and a machine-learning based spectrum classifier) and determine sets of criteria that would provide us co…
This document presents a research plan for a 4-month visit to the University of Milan (Italy), to work with Prof. Luigi Guzzo. The proposal is based on the exploitation of the "VIMOS Public Extragalactic Redshift Survey" (VIPERS), of which Prof. Guzzo is the leading scientist, in the context of our FAPESP project "Unifying Galaxy Evolution and Cosmology with Massive Dark-Energy Surveys". …
