The Dark Matter Distribution in the Spiral \(NGC~3198\) out to 0.22 \(R_{vir}\)

We use recent very extended HI kinematics (out to 48 kpc) along with previous H\(\alpha\) kinematics of the spiral galaxy NGC 3198 in order to derive its distribution of dark matter (DM). First, we used a chi-square method to model the rotation curve (RC) of this galaxy in terms of different profile...
