    • Estudo do meio interestelar através de estrelas anãs brancas 

      Manganelli, Marcos Rodrigues (2012) [Trabalho de conclusão de graduação]
      A luz emitida pelas estrelas é espalhada pelas partículas do meio interestelar ao se propagar através dele. Isso causa a extinção da luz e deixa os espectros observados “mais avermelhados”. A extinção deve ser levada em ...

    • Star formation in distant starburst galaxies 

      Bonatto, Charles Jose; Bica, Eduardo Luiz Damiani; Pastoriza, Miriani Griselda; Alloin, Danielle Marie (2000) [Artigo de periódico]
      This paper discusses the stellar population content of distant (5 000kms−1 VR 16 000kms−1) galaxies with enhanced star-formation activity. Distinction is made between isolated galaxies and galaxies morphologically disturbed, ...

    • The mysterious object around Mrk 1172 

      Lassen, Augusto Eduardo (2020) [Dissertação]
      A nebular region with strong emission lines is found near the quiescent Early- Type Galaxy (ETG) Mrk 1172. Extensive studies are performed in order to de- termine the nature of this object, since to the best of our knowledge ...

    • The need for multicomponent dust attenuation in modeling nebular emission : constraints from SDSS-IV MaNGA 

      Ji, Xihan; Yan, Renbin; Bundy, Kevin; Boquien, Médéric; Schaefer, Adam L.; Belfiore, Francesco; Bershady, Matthew A.; Drory, Niv; Li, Cheng; Westfall, Kyle B.; Lin, Zesen; Bizyaev, D.; Law, David R.; Riffel, Rogério; Riffel, Rogemar André (2023) [Artigo de periódico]
      A fundamental assumption adopted in nearly every extragalactic study that analyzes optical emission lines is that the attenuation of different emission lines can be described by a single attenuation curve, scaled by a ...
