Kinematical and Dynamical Modeling of Elliptical Galaxies
G. A. Mamon, E. Lokas, A. Dekel +2
Elements of kinematical and dynamical modeling of elliptical galaxies (Es) are presented. In projection, NFW models resemble Sersic models, but with a very narrow range of shapes (…
Lost and found dark matter in elliptical galaxies
Felix Stoehr, Gary A. Mamon, Avishai Dekel +1
The kinematical properties of elliptical galaxies formed during the mergers of equal mass, stars+gas+dark matter spiral galaxies are compared to the observed low velocity dispersio…
Lost & Found Dark Matter in Elliptical Galaxies
A. Dekel, F. Stoehr, G. A. Mamon +3
There is strong evidence that the mass in the Universe is dominated by dark matter, which exerts gravitational attraction but whose exact nature is unknown. In particular, all gala…
The structure of voids
Stefan Gottloeber, Ewa Lokas, Anatoly Klypin +1
Using high resolution N-body simulations we address the problem of emptiness of giant 20 Mpc/h diameter voids found in the distribution of bright galaxies. Are the voids filled by…
Black hole to bulge mass correlation in Active Galactic Nuclei: A test for the simple unified formation scheme
Y. P. Wang, P. L. Biermann, A. Wandel
A mass correlation of central black holes and their spheroids ~0.002(within a factor of three) is suggested by Hubble Space Telescope (HST) and various ground-based CCD photometrie…
