High-Redshift Clumpy Disks and Bulges in Cosmological Simulations (2009)
Ceverino, Daniel, Dekel, Avishai, Bournaud, Frederic
We analyze the first cosmological simulations that recover the fragmentation of high-redshift galactic discs driven by cold streams. The fragmentation is recovered owing to an AMR resolution better...
Dekel, Avishai, Sari, Re'em, Ceverino, Daniel
We present a simple theoretical framework for massive galaxies at high redshift, where most of the assembly and star formation occurred. The evolution is governed by the interplay between fueling by...
The role of stellar feedback in the formation of galaxies (2007)
Ceverino, Daniel, Klypin, Anatoly
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 models of the ISM...
The role of Stellar Feedback in the formation of galactic disks and bulges in a LCDM Universe (2007)
Ceverino, Daniel, Klypin, Anatoly
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+Hydrodynamics simulations of...
Resonances in Barred Galaxies (2007)
Ceverino, Daniel, Klypin, Anatoly
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 of the main effects...
The role of resonances in barred galaxies (2005)
Ceverino, Daniel, Klypin, Anatoly
The dynamics of the inner disk of many galaxies is dominated by bars. As a result, resonances between the bar and the disk become an important factor. In order to detect resonances, we measure...
