  • SANTANA, Leandro; http://lattes.cnpq.br/7320009315739681 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-08-27)
    In this dissertation, after a brief review of the elements present in differential geometry, we present Penrose’s Singularity Theorem (1965) and rewrite it from the perspective of disformal transformations. Without ...
  • SIQUEIRA, Marcos Felipe Faria Terra; http://lattes.cnpq.br/9980188384470104 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-03-05)
    Differential spectrophotometry of transiting Hot-J´upiters has shown to be a promising technique to characterize the upper atmosphere of these planets, without the necessity of spatially resolving it from its host star. ...
  • RANA, Rodrigo Galhardo; http://lattes.cnpq.br/3353555630220552 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-12-16)
    In this work we study the main properties and algebraic structures of the conformal field theories. In particular, we consider classical and quantum field theories for free bosonic and fermionic systems with differents ...
  • MARQUES, Bárbara Luiza de Miranda; http://lattes.cnpq.br/8252593637622853 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-08-10)
    In this work, four planetary nebulae (PNe) were studied through the analysis of integral field spectroscopy (IFS) data, obtained in one of the four telescopes that form the Very Large Telescope (VLT, European Southern ...
  • BRITO, Monique Marques de; http://lattes.cnpq.br/4896765034122506 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-08-24)
    Planetary nebulae (PNe) and HII regions represent important tools with regard to determining chemical abundances and exploring radial abundance gradients in spiral galaxies. Both objects configure stellar populations with ...
  • SANTOS, Patricia Maria dos; http://lattes.cnpq.br/5762476423634852 (Universidade Federal de ItajubáBrasilIFQ - Instituto de Física e QuímicaPrograma de Pós-Graduação: Mestrado - FísicaUNIFEI, 2020-10-15)
    Planetary Nebulae (PNe) are objects of very complex morphologies and the details of their spatial structure formation are still object of investigation. There are few works that take into account the three-dimensional ...
