Welcome to the L-Galaxies webpage! L-Galaxies is a cosmological-scale semi-analytic simulation of galaxy evolution, which runs on the dark matter halo "merger trees" generated by N-body simulations of hierarchical structure formation.
Thanks to its semi-analytic nature, L-Galaxies is able to model the evolution of many millions of galaxies from very early times to the present day much more efficently than hydrodynamical simulations of comparable size. This makes L-Galaxies ideal for testing models of astrophysical processes, as well as studying statistically-significant samples of galaxies, including relatviely rare systems such as galaxy clusters and supermassive black holes. For more information on the physics models included in L-Gala
The latest public version of the simulation is L-Galaxies 2020 ( Henriques et al. 2020 ). The code and sample outputs from this and other versions can be downloaded here . Output data can also be obtained from the Millennium Database SQL interface or via TOPCAT . For access to the full database (including L-Galaxies 2020 tables), see here .
