Gas flow and dark matter in the inner parts of early-type barred galaxies I. SPH simulations and comparison with the observed kinematics

Perez, I; Fux, Roger; Freeman, Kenneth

Description

The dynamical simulations run in the potential derived from the light distribution of 5 late-type barred spiral galaxies were discussed. Simulations were run for potentials obtained from the I-band light distribution and from the composite of a H-band images at the centre and I-band image in the outer isophotes. Such models show differences in the gas distribution resulting from the higher dust absorption in the central regions of the I-band image. It was found that the gravitational field in...[Show more]
