Ramses is an open source code to model astrophysical systems. It describes self-gravitating, magnetised, compressible, radiative fluid flows with Adaptive Mesh Refinement (AMR), and has been widely used for cosmological simulations of the Universe, isolated as well as cosmological resimulations of individual galaxies, simulations of molecular clouds, star formation, supernovae remnants, accretion disks around black holes and planets. Ramses was written by Romain Teyssier, and is now used and developed by a growing community of astrophysicists all around the world, with many groups in France, United Kingdom, Danemark, South Korea and the United States.
The goal of this website is to promote the activities of the Ramses community in France and internationally. It is edited by the RAMSES SNO (see this page for more details about this structure).

After the new Ramses Meeting in Korea, it’s time for a new Ramses release! On the menu, a lot of performance improvements, many many bugs corrections, an armada of new tests, a brand new developer docs and a bunch of convenient new features.

Horizon Run 5 (HR5, not to be mistaken with The Horizon Simulations), introduced by Lee et al. (2021) is a cosmological hydrodynamical simulation which captures the properties of the Universe on a Gpc scale while achieving a resolution of 1 kpc, aims to study the effect of large-scale perturbations on formation of galaxies and clusters.…
