Does Dark Matter Exist?
J. A. Sellwood, A. Kosowsky
The success of the Lambda-CDM model on large scales does not extend down to galaxy scales. We list a dozen problems of the dark matter hypothesis, some of which arise in specific m…
The Disk and Dark Halo Mass of the Barred Galaxy NGC 4123. II. Fluid-Dynamical Models
Benjamin J. Weiner, J. A. Sellwood, T. B. Williams
We report a dynamical determination of the separate contributions of disk and dark halo masses to the rotation curve of a spiral galaxy. We use fluid-dynamical models of gas flow i…
The Disk and Dark Halo Mass of the Barred Galaxy NGC 4123. I. Observations
Benjamin J. Weiner, T. B. Williams, J. H. van Gorkom +1
The non-circular streaming motions in barred galaxies are sensitive to the mass of the bar and can be used to lift the degeneracy between disk and dark matter halo encountered when…
