The role of stellar feedback in the formation of galaxies
Daniel Ceverino, Anatoly Klypin
We develop a new realistic prescription for modeling the stellar feedback, which minimizes any ad hoc assumptions about sub-grid physics. We start with developing high resolution m…
Connecting Galaxy Disk and Extended Halo Gas Kinematics
G. G. Kacprzak, C. W. Churchill, C. C. Steidel +3
We have explored the galaxy disk/extended halo gas kinematic relationship using rotation curves (Keck/ESI) of ten intermediate redshift galaxies which were selected by MgII halo ga…
The role of Stellar Feedback in the formation of galactic disks and bulges in a LCDM Universe
Daniel Ceverino, Anatoly Klypin
Although supernova explosions and stellar winds happens at scales bellow 100 pc, they affect the interstellar medium(ISM) and galaxy formation. We use cosmological N-body+Hydrodyna…
The Fossil Phase in the Life of a Galaxy Group
Alexander M. von Benda-Beckmann, Elena D'Onghia, Stefan Gottloeber +4
We investigate the origin and evolution of fossil groups in a concordance LCDM cosmological simulation. We consider haloes with masses between $(1-5)\times10^{13} \hMsun$ and study…
The virialized mass of dark matter haloes
A. J. Cuesta, F. Prada, A. Klypin +1
(Abridged) Virial mass is used as an estimator for the mass of a dark matter halo. However, the commonly used constant overdensity criterion does not reflect the dynamical structur…
Properties of voids in the Local Volume
Anton Tikhonov, Anatoly Klypin
Current explanation of the overabundance of dark matter subhalos in the Local Group (LG) indicates that there maybe a limit on mass of a halo, which can host a galaxy. This idea ca…
Voids in the Local Volume: a limit on appearance of a galaxy in a DM halo
Anton V. Tikhonov, Anatoly A. Klypin
Current explanation of the overabundance of dark matter subhalos in the Local Group (LG) indicates that there maybe a limit on mass of a halo, which can host a galaxy. This idea ca…
Testing gravity with motion of satellites around galaxies: Newtonian gravity against Modified Newtonian Dynamics
A. Klypin, F. Prada
The motion of satellite galaxies around normal galaxies at distances 50-500 kpc provides a sensitive test for the theories. We study the surface density and the velocities of satel…
Resonances in Barred Galaxies
Daniel Ceverino, Anatoly Klypin
The inner parts of many spiral galaxies are dominated by bars. These are strong non-axisymmetric features which significantly affect orbits of stars and dark matter particles. One…
