Momentum-conserving self-gravity in the phantom smoothed particle hydrodynamics code. Parallel dual tree traversal for the symmetric fast multipole method
Yann Bernard, Timothée David-Cléris, Daniel J. Price +1
Tree codes that approximate groups of distant particles with multipole expansions are the standard way to accelerate the computation of self-gravity on particles. While momentum-co…

Large dust fractions can prevent the propagation of soundwaves
Timothée David--Cléris, Guillaume Laibe
Dust plays a central role in several astrophysical processes. Hence the need of dust/gas numerical solutions, and analytical problems to benchmark them. In the seminal dustywave pr…
