    • Com les Varietats Invariants formen Espirals i Anells en Galàxies barrades 

      Romero Gómez, Mercè; Sánchez-Martín, Patricia; Masdemont Soler, Josep (2014)
      Article
      Open Access
      L'espectacularitat de les galàxies barrades consisteix no solament en la presència de la barra, allargada en el centre de la galàxia, sinó també en els braços espirals o anells que es desenvolupen en les parts exteriors. ...

      In a series of papers, we propose a theory to explain the formation and properties of rings and spirals in barred galaxies. The building blocks of these structures are orbits guided by the manifolds emanating from the ...
    • Warp evidence in precessing galactic bar models 

      Sanchez Martin, P; Romero Gómez, Mercè; Masdemont Soler, Josep (EDP Sciences, 2016-04-01)
      Article
      Open Access
      Most galaxies have a warped shape when they are seen edge-on. The reason for this curious form is not completely known so far, so in this work we apply dynamical system tools to contribute to its explanation. Starting from ...
