Galactic Bars in Cosmological Context
Isaac Shlosman
Galactic disks can form in asymmetric potentials of the assembling dark matter (DM) halos, giving rise to the first generation of gas-rich bars. Properties of these bars differ fro…
Disk Evolution and Bar Triggering Driven by Interactions with Dark Matter Substructure
Emilio Romano-Diaz, Isaac Shlosman, Clayton Heller +1
We study formation and evolution of bar-disk systems in fully self-consistent cosmological simulations of galaxy formation in the LCDM WMAP3 Universe. In a representative model we…
Dark Matter Halos: Velocity Anisotropy -- Density Slope Relation
Amir Zait, Yehuda Hoffman, Isaac Shlosman
Dark matter (DM) halos formed in CDM cosmologies seem to be characterized by a power law phase-space density profile. The density of the DM halos is often fitted by the NFW profile…
Structure Formation Inside Triaxial Dark Matter Halos: Galactic Disks, Bulges and Bars
Clayton Heller, Isaac Shlosman, Lia Athanassoula
We investigate the formation and evolution of galactic disks immersed in assembling live DM halos. Disk/halo components have been evolved from the cosmological initial conditions a…
Evolution of Phase-Space Density in Dark Matter Halos
Yehuda Hoffman, Emilio Romano-Diaz, Isaac Shlosman +1
The evolution of the phase-space density profile in dark matter (DM) halos is investigated by means of constrained simulations, designed to control the merging history of a given D…
Building Galactic Disks in Triaxial Dark Matter Halos
Isaac Shlosman
We review our recent work on the formation and evolution of disks with in triaxial dark matter (DM) halos by means of numerical simulations, including star formation and feedback f…
