Title: Gravitational perturbations of black holes with spherical symmetryDescription: Gravitational perturbations refer to small deviations or fluctuations in the gravitational field of an object. When considering black holes with spherical symmetry, gravitational perturbations can be analyzed using the theory of general relativity. In particular, it is possible to study the behavior of gravitational waves as they propagate through spacetime around a black hole with spherical symmetry. These gravitational waves can be generated by a variety of sources, such as the collision of two black holes or the collapse of a massive star. An important feature of the gravitational perturbations around a black hole with spherical symmetry is that they can be separated into different modes. These modes correspond to different angular and radial oscillations of the gravitational field and can be described mathematically using spherical harmonics. Axial modes correspond to perturbations that preserve the spherical symmetry of the black hole, while polar modes correspond to perturbations that break the spherical symmetry. Therefore, the different modes of a black hole refer to the different types of perturbations that can be applied to it, resulting in different types of oscillations. Show less

Differential and Integral Calculus Monitor I

• Aug 2022 - Dec 2022

During the internship period, the intern provided 4 hours a week to assist students in the discipline in a synchronous face-to-face manner. On Tuesdays and Thursdays, from 6 pm to 8 pm, in room 07 (Núcleo de Projetos) in the Department of Mathematics. In the monitoring classes, the intern met with the students in order to clarify doubts about the lists. In addition, the intern was willing to answer questions from students about the content studied with the teacher responsible for the discipline. Students were not required to participate in tutoring classes, so their attendance was not uniform throughout the internship period. The period of greatest demand by students occurred on dates close to the exams. Show less

Gravitational Waves in Post-Newtonian Regime

• Mar 2021 - Mar 2022

The existence of gravitational waves is among the first and most fundamental predictions of general relativity. Indirect observations of this phenomenon were carried out in 1974 by Russell A. Hulse and Joseph H. Taylor Jr when studying the period variation of the PSR1913+16 binary system, which earned them the Nobel Prize in Physics in 1993. More recently Rainer Weiss, Kip Thorne and Barry Barish were awarded the 2017 Nobel Prize in Physics for their contributions to the construction of the LIGO detector, which for the first time directly detected gravitational waves. The direct detection of gravitational waves opens up a wide range of research possibilities related to the topic. From astrophysics to the foundations of general relativity and alternative theories. Making this a line of research with potentially very promising results. In this project we will study the theoretical and fundamental basis of the generation of gravitational waves in the context of general relativity. Show less

Asteroid Family Identification with Machine Learning Algorithms

• Mar 2019 - Mar 2020

The identification of asteroid families has become an increasingly common practice among researchers and, consequently, there is a growing need to develop software that makes this process increasingly faster and more efficient. For decades, these families were successfully identified using the Hierarchical Clustering Method. This method consists of analyzing and calculating the metric distance between the studied asteroid and a reference body, if the distance from the asteroid to the body is less than the characteristic threshold value, called the cutoff value, the body is then assigned to the reference asteroid. family and used as the next body of reference until another candidate is identified. Recently, the new Clustering method by Machine Learning Algorithms is being introduced for the purpose of identifying and classifying asteroid families. Show less
