Scaling limits of critical branching random walks and their snakes

We study scaling limits of $\mathbb R^d$-valued branching random walks (BRWs for short) in the following setting: indexing-trees are Galton-Watson trees with critical offspring distribution which are assumed, when appropriately rescaled, to converge to a critical $\psi$-L\'evy tree; conditional on the indexing tree, th...
