Toy Models for Galaxy Formation versus Simulations
A. Dekel, A. Zolotov, D. Tweed +3
We describe simple useful toy models for key processes of galaxy formation in its most active phase, at z > 1, and test the approximate expressions against the typical behaviour in…

The largest galaxies acquire their mass early on, when the Universe is still youthful. Cold streams violently feed these young galaxies a vast amount of fresh gas, resulting in ver…

Building Merger Trees from Cosmological N-body Simulations
D. Tweed, J. Devriendt, J. Blaizot +2
Although a fair amount of work has been devoted to growing Monte-Carlo merger trees which resemble those built from an N-body simulation, comparatively little effort has been inves…
