Galaxy Dynamics Conference 2005.
A website of my graduate advisor Anatoly Klypin with a very interesting discussion (Look at rotation curves).
He has a new web page but you might need a passwd.
Here you can see the fate of a galactic bar inside a prolate cuspy halo
The Internal Structure of Dark Matter Halos
The following Plots show predicted rotation curves for a disk galaxy with
a cuspy halo(Cvir =12,Mvir=5.e10,Om0=.3,Overdens=340,h=0.7rc=2.50=rd. The plot to the right has a central radial
velocity dispersion of 30 km/s. Notice the almost linear growth of the velocity. The plot to the left shows the same galaxy just with a central velocity dispersion of 3 km/s.
This figure shows the velocity field and the PV diagram for two
different view angles of neutral gas in a galaxy with a cuspy halo. In frame 1, green represents
cells with at least 10% of neutral gas and less than 400 pc away from the disk plane. Cyan represents
the young stellar component(younger thatn 50 million yrs). Lower left panel shows the PV diagram for the young stellar component.
All the PVD are made with data inside 1 kpc from the center.
This figure shows the same galaxy. Upper left frame shows the spatial
distribution of the stellar component younger than 10 million yrs (cyan). Green shows the neutral gas and
blue is the ionized gas. Lower right fram shows the PVD for the stellar component inside 1 kpc.
Upper right frame shows the same PVD for neutral gas and lower right frame shows the PVD for ionized gas.
All the PVD are made with data inside 0.5 kpc from the center.
This figure shows the ionized gas (blue), young stellar component (cyan)
panel 1. The PV diagram corresponding to the ionized gas is shown in the lower right panel.
This is a galaxy that contains several satellites inside the virial radius. The asymmetric distribution of material in the dark matter halo triggers a lopsided configuration in the disk.
