Open AccessMost galaxies have a warped shape when they are seen from an edge-on point of view. In this work we apply dynamical system methods to find an explanation of this phenomenon that agrees with its abundance among galaxies, ...

Open AccessWe study the dynamics near the unstable Lagrangian points in galactic bar models using dynamical system tools in order to determine the global morphology of a barred galaxy. We aim at the case of non-autonomous models, in ...

Open AccessEphemerides describe the position and velocity of a celestial object as a function of time. The ephemerides data are obtained by solving the fundamental equations of motion of the body, which is obtained by applying the ...
Residual-based stabilization of the finite element approximation to the acoustic perturbation equations for low Mach number aeroacoustics Guasch Fortuny, Oriol; Sánchez Martín, Patricia; Pont Ribas, Arnau; Baiges Aznar, Joan; Codina, Ramon (2016-12)
Open AccessThe acoustic perturbation equations (APE) are suitable to predict aerodynamic noise in the presence of a non-uniform mean flow. As for any hybrid computational aeroacoustics approach, a first computational fluid dynamics ...
