L-GALAXIES 2020: Spatially resolved cold gas phases, star formation and chemical enrichment in galactic discs
Bruno Henriques, Rob Yates, Jian Fu +5
We have updated the Munich galaxy formation model, L-Galaxies, to follow the radial distributions of stars and atomic and molecular gas in galaxy discs. We include an H2-based star…
MEGA: Merger graphs of structure formation
William J. Roper, Peter A. Thomas, Chaichalit Srisawat
When following the growth of structure in the Universe, we propose replacing merger trees with merger graphs, in which haloes can both merge and split into separate pieces. We show…
Cosmic CARNage II: the evolution of the galaxy stellar mass function in observations and galaxy formation models
Rachel Asquith, Frazer R. Pearce, Omar Almaini +24
We present a comparison of the observed evolving galaxy stellar mass functions with the predictions of eight semi-analytic models and one halo occupation distribution model. While…
Sussing Merger Trees: Stability and Convergence
Yang Wang, Frazer R. Pearce, Alexander Knebe +15
Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. (2013) co…
nIFTy Cosmology: Comparison of Galaxy Formation Models
Alexander Knebe, Frazer R. Pearce, Peter A. Thomas +33
We present a comparison of 14 galaxy formation models: 12 different semi-analytical models and 2 halo-occupation distribution models for galaxy formation based upon the same cosmol…
