| Abstract: | The bar formation is still an open problem in modern astrophysics. In this paper we present numerical simulations performed
with the aim of analyzing the growth of the bar instability inside stellar-gaseous disks, where the star formation is triggered,
and a central black hole is present. The aim of this paper is to point out the impact of such a central massive black hole
on the growth of the bar. We use N-body-SPH simulations of the same isolated disk-to-halo mass systems harboring black holes
with different initial masses and a different energy feedback on the surrounding gas. We compare the results of these simulations
with the one of the same disk without a black hole in its center. We make the same comparison (disk with and without black
hole) for a stellar disk in a fully cosmological scenario. A stellar bar, lasting 10 Gyrs, is present in all our simulations. |
