Formation of disk galaxies: feedback and the angular momentum problem
J. Sommer-Larsen, S. Gelato, H. Vedel
When only cooling processes are included, smoothed-particle hydrodynamical simulations of galaxy formation in a Cold Dark Matter hierarchical clustering scenario consistently produ…
The Mass and Mass-to-Light Ratio for Clusters of Galaxies at Large Radii
H. Vedel, F. D. A. Hartwick
We construct models describing the velocity field in the infall regions of clusters. The velocity field is the superposition of a systematic component and a "noise" component accou…
On the Global Structure of Self-gravitating Disks for Softened Gravity
Jesper Sommer-Larsen, Henrik Vedel, Uffe Hellsten
Effects of gravitational softening on the global structure of self-gravitating disks in centrifugal equillibrium are examined in relation to hydrodynamical/gravitational simulation…
The Structure of Isothermal, Self-gravitating Gas Spheres for Softened Gravity
Jesper Sommer-Larsen, Henrik Vedel, Uffe Hellsten
A theory for the structure of isothermal, self-gravitating gas spheres in pressure equilibrium in a softened gravitational field is developed. The one parameter spline softening pr…
