Stellar Bar evolution in the absence of dark matter halo

School
ASTRONOMY

I report the results of some high-resolution N-body simulations in which the evolution of stellar bar is measured in isolated galactic models. Some models follow the standard view and possess rigid/live dark matter halos. On the other hand, we construct a numeric model in which there is no dark matter halo, and instead, the gravitational force is modified following the prescription introduced in MOG. MOG is a covariant generalization of Einstein's general relativity which has been introduced to address the dark matter problem without invoking exotic particles. I first review this theory from astrophysical and cosmological point of views, and ...
