cosmological context, the" Semi-Analytic Galaxy Evolution" model, or sage for short. 5 sage …

Building disc structure and galaxy properties through angular momentum: the Dark Sage semi-analytic model

ARH Stevens, DJ Croton…�- Monthly Notices of the�…, 2016 - academic.oup.com
We present the new semi-analytic model of galaxy evolution, Dark Sage, a heavily modified
version of the publicly available sage code. The model is designed for detailed evolution of …

Where do galaxies end? Comparing measurement techniques of hydrodynamic-simulation galaxies' integrated properties

ARH Stevens, M Martig, DJ Croton…�- Monthly Notices of the�…, 2014 - academic.oup.com
… Because h is a dimensionless constant and not a unit (see Croton 2013), we dissociate
explicit factors of h from relevant units, in favour of it either being attached to the number in …

The Three Hundred project: a large catalogue of theoretically modelled galaxy clusters for cosmological and astrophysical applications

…, DJ Croton, M Sinha, ARH Stevens…�- Monthly Notices of�…, 2018 - academic.oup.com
We introduce the the three hundred project, an endeavour to model 324 large galaxy clusters
with full-physics hydrodynamical re-simulations. Here we present the data set and study …

How to get cool in the heat: comparing analytic models of hot, cold and cooling gas in haloes and galaxies with EAGLE

ARH Stevens, CP Lagos, S Contreras…�- Monthly Notices of�…, 2017 - academic.oup.com
We use the hydrodynamic, cosmological EAGLE simulations to investigate how the hot gas
in haloes condenses to form and grow galaxies. We select haloes from the simulations that …

Cosmic CARNage I: on the calibration of galaxy formation models

…, AN Ruiz, C Srisawat, ARH Stevens…�- Monthly Notices of�…, 2018 - academic.oup.com
We present a comparison of nine galaxy formation models, eight semi-analytical, and one
halo occupation distribution model, run on the same underlying cold dark matter simulation (…

Cosmic CARNage II: the evolution of the galaxy stellar mass function in observations and galaxy formation models

…, C Power, C Srisawat, ARH Stevens…�- Monthly Notices of�…, 2018 - academic.oup.com
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 …

[PDF][PDF] Where do galaxies end? A study of hydrodynamic-simulation galaxies and their integrated properties

ARH Stevens, M Martig, DJ Croton, Y Feng - 2014 - Citeseer
Many techniques have been used in the literature for determining which particles or cells in
a hydrodynamic simulation are attached to a galaxy. Often these invoke a spherical aperture …

Quantifying the impact of mergers on the angular momentum of simulated galaxies

CP Lagos, ARH Stevens, RG Bower…�- Monthly Notices of�…, 2018 - academic.oup.com
We use eagle to quantify the effect galaxy mergers have on the stellar specific angular
momentum of galaxies, j stars . We split mergers into dry (gas-poor)/wet (gas-rich), major/minor …
