RASCAS (for RAdiative SCattering in Astrophysical Simulations) is a massively parallel code for performing radiative transfer in AMR simulations with astrophysical applications in mind. RASCAS has been designed to be easily customisable and to process simulations of arbitrarily large sizes on large supercomputers. Developed initially for Lyman-alpha applications, it has now been applied to line transfer in general (resonant, like Mg II, or not, like H-alpha), and even continuum.

With a growing community in France and abroad, it is now time for a first meeting gathering the community of users and developers. 

We expect all participants to give a talk (short or long) to introduce themselves and the projects they have with RASCAS.

Participation is free of charge, but registration is mandatory. 

The RASCAS User Meeting 2026 will take place in Lyon, at the École Normale Supérieure de Lyon, site Monod (46 allée d'Italie 69007 Lyon), in amphitheater I. The closest metro station is Debourg on metro line B.
