Galaxy formation using halo merger histories taken from N-body simulations
John C. Helly, Shaun Cole, Carlos S. Frenk +3
We develop a hybrid galaxy formation model which uses outputs from an N-body simulation to follow the merger histories (or ``merger trees'') of dark matter halos and treats baryoni…

A Comparison of Gas Dynamics in SPH and Semi-analytic Models of Galaxy Formation
John C. Helly, Shaun Cole, Carlos S. Frenk +4
We compare the results of two techniques used to calculate the evolution of cooling gas during galaxy formation: Smooth Particle Hydrodynamics (SPH) simulations and semi-analytic m…
