Pb. Tissera et R. Domingueztenreiro, DARK-MATTER HALO STRUCTURE IN CDM HYDRODYNAMICAL SIMULATIONS, Monthly Notices of the Royal Astronomical Society, 297(1), 1998, pp. 177-194
We have carried out a comparative analysis of the properties of dark m
atter haloes in N-body and hydrodynamical simulations, We analyse thei
r density profiles, shapes and kinematical properties with the aim of
assessing the effects that hydrodynamical processes might produce on t
he evolution of the dark matter component. The simulations performed a
llow us to reproduce dark matter haloes with high resolution, although
the range of circular velocities is limited. We find that for haloes
with circular velocities of [150-200] km s(-1) at the virial radius, t
he presence of baryons affects the evolution of the dark matter compon
ent in the central region, modifying the density profiles, shapes and
velocity dispersions, We also analyse the rotation velocity curves of
disc-like structures and compare them with observational results. (C)
