The dark matter halo shape of edge-on disk galaxies: IV. UGC 7321

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


This is the fourth paper in a series in which we attempt to put constraints on the flattening of dark halos in disk galaxies. We observed for this purpose 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. As reported in earlier papers in this series we have for this purpose analysed the HI channel maps to accurately measure all four functions that...[Show more]
