Constraints from Dynamical Friction on the Dark Matter Content of Barred Galaxies
Victor P. Debattista, J. A. Sellwood
We show that bars in galaxy models having halos of moderate density and a variety of velocity distributions all experience a strong drag from dynamical friction unless the halo has…
The Stability of Disks in Cusped Potentials
J A Sellwood, N W Evans
We confirm that a high rate of shear at the center is able to stabilize an entire stellar disk against bar-forming (m=2) modes, irrespective of the dark halo density. Our simulatio…
Is a Simple Collisionless Relic Dark Matter Particle Ruled Out?
J. A. Sellwood
The central densities of dark matter (DM) halos are much lower than predicted in cold DM models of structure formation. Confirmation that they have cores with a finite central dens…
Disk heating and stellar migration in galaxies
J. J. Binney, J. A. Sellwood
The paper claimed that significant radial migration of stars in a stellar disk like that of the Milky Way could not occur. We now think that while the treatment of the effects of m…
