Simulaciones de formación de galaxias disco barreadas

| Sumario: | In this work we present a study of the formation and evolution of two galaxies selected from a series of numerical cosmological hydrodynamical simulations called GIMIC. The first one is a galaxy with a central bar at redshift z = 0 formed between 9 t [Gyr] 11. At this time, the galaxy accretes gas from distinct directions forming a ring located in a different plane respect to the galaxy disc. This disc transfers its angular momentum to the gas and halo decaying its pattern speed and becoming a bar. The second one is a galaxy that had a bar until a time t 10 Gyr. After this time, the bar gradually disintegrate until redshift z = 0 (t = 13.6 Gyr). This disintegration is unusual and may be due to strong perturbations originated by the proximity of a massive satellite at t 10 Gyr. |
