The dark matter halo shape of edge-on disk galaxies. I. HI observations.

O'BRIEN J.C., FREEMAN K.C., VAN DER KRUIT P.C. and BOSMA A.

Abstract (from CDS):

This is the first paper of a series in which we will attempt to put constraints on the flattening of dark halos in disk galaxies. We observe 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. In this paper, we define a sample of 8 HI rich late-type galaxies suitable for this purpose and present the HI observations.
