Cold streams in early massive hot haloes as the main mode of galaxy formation
A. Dekel, Y. Birnboim, G. Engel +7
The massive galaxies in the young universe, ten billion years ago, formed stars at surprising intensities. Although this is commonly attributed to violent mergers, the properties o…
Scaling Relations and the Fundamental Line of the Local Group Dwarf Galaxies
Joanna Woo, Stephane Courteau, Avishai Dekel
We study the scaling relations between global properties of dwarf galaxies in the Local Group. In addition to quantifying the correlations between pairs of variables, we explore th…
Tidal Effects and the Environment Dependence of Halo Assembly
Oliver Hahn, Cristiano Porciani, Avishai Dekel +1
We explore a possible origin for the puzzling anti-correlation between the formation epoch of galactic dark-matter haloes and their environment density. This correlation has been r…
Merger Rates of Dark-Matter Haloes
Eyal Neistein, Avishai Dekel
We derive analytic merger rates for dark-matter haloes within the framework of the Extended Press-Schechter (EPS) formalism. These rates become self-consistent within EPS once we r…
Downsizing by Shutdown in Red Galaxies
A. Cattaneo, A. Dekel, S. M. Faber +1
We address the origin of the `downsizing' of elliptical galaxies, according to which the stars in more massive galaxies formed earlier and over a shorter period than those in less…
