Polynomial propagation of moments and global existence for a Vlasov–Poisson system with a point charge
Annales de l'I.H.P. Analyse non linéaire, Tome 32 (2015) no. 2, pp. 373-400.

In this paper, we extend to the case of initial data constituted of a Dirac mass plus a bounded density (with finite moments) the theory of Lions and Perthame [8] for the Vlasov–Poisson equation. Our techniques also provide polynomially growing in time estimates for moments of the bounded density.
