We study the stellar bar growth in high-resolution numerical galaxy models with and without dark matter halos. In all models, the galactic disk is exponential, and the halos are rigid or live Plummer spheres. More specifically, ...

We study the evolution of simulated disk galaxies in the context of a nonlocal theory of gravity. In this theory, the appearance of the dark matter problem in cosmology and astrophysics is a manifestation of the nonlocality ...

We study the local and global stability of thin galactic disks in the context of MOG (modified

gravity). In the case of local stability, we show that at large distances from the center, galactic

disks are ...
