The dark matter halo shape of edge-on disk galaxies. II. Modelling the HI observations: methods

O'Brien, J; Freeman, Kenneth; van der Kruit, P C

Description

This is the second paper of a series in which we attempt to put constraints on the flattening of dark halos in disk galaxies. For this purpose, we observe the Hi in edge-on galaxies, where it is in principle possible to measure the force field in the halo vertically and radially from gas layer flaring and rotation curve decomposition respectively. To calculate the force fields, we need to analyse the observed XV diagrams to accurately measure all three functions that describe the planar...[Show more]
