A chromodynamical analysis of S0 galaxies with globular clusters and planetary nebulae
(2017) [Dissertação]Galaxias lenticulares são consideradas como uma fase de transição entre galáxias early-type e late-type, uma vez que apresentam características comuns a tanto um quanto ao outro tipo. Devido a isto, o estudo da evolução ... -
Compact starburst galaxies in groups of dwarf galaxies
(2022) [Dissertação]The mechanisms behind the peculiar characteristics of Compact Starburst Galaxies (CSBGs), such as extremely high star formation rates (SFRs) and low gas metallicities, are still poorly understood. They have formed a large ... -
Estudo de aglomerados estelares no complexo HII NGC 6357 com o VISTA Variables in the Via Lactea
(2014) [Tese]Complexos de formação estelar são os principais blocos de formação das galáxias. O estudo da estrutura e do conteúdo estelar de aglomerados imersos nesses complexos permite conhecer melhor os processos de formação estelar ... -
Extragalactic stellar clusters in high density environments
(2021) [Tese]Stellar clusters are ubiquitous in all luminous galaxies and have the potential to be used as tracers of galaxy formation and evolution if we understand their formation and assembly into their host systems. They have been ... -
Investigando as populações estelares de galáxias Starburst através de espectroscopia no infravermelho próximo
(2014) [Dissertação]Utilizamos espectros obtidos com o espectrógrafo SpeX (em 0.8-2.4μm), anexado ao telescópio de 3m IRTF (Infrared Telescope Facility) da NASA, para investigar a distribuição espacial das populações estelares (SPs) em quatro ... -
Revealing the chemical evolution history of the Milky Way halo with RR Lyrae stars
(2021) [Tese]The Galactic Halo is the component of the Milky Way that can preserve the clearest signatures of the accretion of satellites required for the built-up of the Galaxy according to the Λ cold dark matter paradigm. The nature ... -
Spatial distribution of galactic globular clusters : distance uncertainties and dynamical effects
(2017) [Dissertação]We provide a sample of 170 Galactic Globular Clusters (GCs) and analyse its spatial distribution properties. Using a comprehensive dust cloud catalogue, we list the GCs that are behind one or more identified dust clouds ... -
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 rich population of jellyfish galaxies in the Abell 901/2 multi-cluster system at z ~ 0.165
(2020) [Dissertação]The evolution of galaxies can be significantly altered in galaxy clusters as a result of interactions with other galaxies and the intracluster medium that surrounds them. Jellyfish galaxies are the most striking examples ...
