NGC 404, a galaxy without dark matter
We present high resolution (15´´ and 2.5 km/s) HI observations of the S0 gal axy NGC 404. We derive an HI mass of MHI = 6.7 × 107 Msolar, in good agreement with previous measurements. The HI is distributed in a broad annulus and extends out to a diameter of 9´, well beyond the optical diameter of 6´...
