Their formation and dynamics have been widely studied both numerically and observationally. Although numerical simulations in the $\\Lambda$CDM cosmological framework predict the formation of such stellar components, there seems to be a tension between theoretical and observational results. Simulated bars are typically larger in size and have slower pattern speed than observed ones. We study the formation and evolution of barred galaxies, using two $\\Lambda$CDM zoom-in hydrodynamical simulations of the CLUES","authors_text":"Gustavo Yepes, Mario G. Abadi, Ornela F.
