Automorphism groups of right-angled Artin groups

Automorphism groups of free groups have many properties in common with linear groups. For example, they are virtually torsion-free, have finite vcd, and satisfy the Tits alternative. Right-angled Artin groups interpolate between free groups and free abelian groups. We study which of these properties are shared by the automorphism groups of all right-angled Artin groups.
