Query: Boundary amenability of $Out(F_N)$   We prove that $Out(F_N)$ is boundary amenable. This also holds more generally
for $Out(G)$, where $G$ is either a toral relatively hyperbolic group or a
finitely generated right-angled Artin group. As a consequence, all these groups
satisfy the Novikov conjecture on higher signatures.
