Claudia Oliveira holds a degree in Physics from the Federal University of Minas Gerais (1985), a Master's degree (1988) and a PhD (1992) in Astronomy from the University of British Columbia, Canada. She completed her post-doctorate at IAP, Paris and was a fellow for two years at the European Southern Observatory, Chile. She is a professor at the Department of Astronomy of IAG, University of São Paulo, since April 1995, with habilitation in 2001 and currently a full professor (since 2009). She has experience in the area of #8203;#8203;Astrophysics, with an emphasis on galaxies, working mainly on the following topics: groups and clusters of galaxies, galaxy evolution and astronomical instrumentation.

The S-PLUS 12-band photometry offers a unique opportunity to uncover Cataclysmic Variables (CVs) in the Southern celestial hemisphere. These systems, in which a white dwarf captures matter from a companion main-sequence star, are key pieces in the study of stellar structure and evolution. While most of these systems have been identified through variability detection in the optical and/or …
We plan to search for anomalous objects and to do classification of galaxies using machine learning and deep learning techniques. More specifically we have been conducting searches of some rare objects such as quasars, asteroids and mergers and classifying active galaxies. In this project we plan to use the above mentioned techniques to combine LSST, S-PLUS and other large multi-band data…
The Universe is chemically complex, having more than 13 billion years to build the tremendous diversity observed today. All of this complexity, however, has started from roughly two very simple ingredients: hydrogen and helium. The first stars to be born in the Universe were massive and rapidly-evolving, providing the chemical seeds to form the subsequentstellar generation, dubbed as 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…

This project has the long-term goal of preparing for the future use of the Giant Magellan Telescope (GMT), a mega telescope that will be one of the most important infrastructures for the Brazilian community in the coming decades. To this end, we are using data from the ongoing S-PLUS survey, which collects images every night with the Brazilian robotic telescope T80-Sul and a wide-field ca…
The influence and transformations undergone by individual galaxies and galaxy groups upon falling into rich galaxy clusters have been extensively studied, primarily focusing on the innermost regions of these structures where complete spectroscopic information is readily available in the literature. However, the more distant regions from the cluster centers, known as the infall region, up …

This work aims to search for anomalous objects in the Southern Photometric Local Universe Survey (S-PLUS). We focus on quasars and, in particular, those with high redshifts, since these objects are important for studies such as the formation and evolution of the first supermassive black holes and their host galaxies, the reionization era, among others. To find such quasars, we will use ma…

This BEPE project will be conducted under the supervision of Dr. Paula Sánchez Sáez at the European Southern Observatory, during 7 months. The main project focuses on the identification of active galactic nuclei (AGN) with anomalous variability using machine learning techniques applied to data from the Zwicky Transient Facility (ZTF). To achieve this, we will adapt and refine the existing…
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…
