Estudo do meio interestelar através de estrelas anãs brancas
(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
(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
(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
(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 ...
