Dynamics of isolated and interacting disk galaxies via N-body and SPH simulations

Abstract

This project fits into the study of the dynamics of isolated and colliding galaxies, via numerical N-body/SPH simulations. It is divided into twosub-projects:(1) Formation of the Polar Ring Galaxies (PRGs): This project aims to understand the detailed dynamics of the PRGs, systems formed through interactions between galaxies. We have been studying observationally the morphology, chemistry and kinematics of PRGs by opticalimaging and spectroscopy. Now we intend to conduct a series of numerical N-body+SPH simulations, in order to better characterize the parameters that lead to the formation of PRGs, testing stability and lifetime of the rings as afunction of those parameters. We will construct a grid of simulations with which the observed objects may be confronted for the study of their dynamics.(2) Bars and spiral arms dynamics in N-Body+SPH simulations: Galactic disks often present more or less prominent spiral patterns, whose formation is not yet fully understood. We intend to conduct a series of N-body+SPH simulations to investigate the evolution of gas and stars isolated galaxies. The objective is to study the formation and evolution of spiral patterns through changes in certain parameters of the initial models and seek to understand the conditions that favor long-lived(Quasi-Stationary Spiral Structure and Modal-theory) or short-lived (Swing Amplification and Stochastic Self-Propagating Star Formation) scenarios. The simulations will be analyzed using one- and two-dimensional Fourier transforms (FT1D/FT2D) that give us the intensity, lifetime and angular velocity for different spiral patterns in each evolutionary model. This work will be developed in collaboration with Dr. IvânioPuerari (INAOE, Mexico), expert on this subject, which should come to Brazil as a Visiting Researcher for the next six months. (AU)
