| dc.description.abstract | In this thesis we have studied bar formation and evolution using N-body simulations. We
have focused on the effect of bulge mass and concentration on bar formation and evolution,
and derived a new bar formation criterion. We also tested the criterion with observations
collected from literature. We then investigated the effect of bulge mass on bar pattern speed
since observations do not give a clear idea of the nature and origin of slow and fast of bars
in galaxies. Bars also a potential candidate for changing the dark matter profile in the central
regions of galaxies as they transports angular momentum from disk to the dark halo. We have
also studied this effect using N-body simulations | en_US |
