| This is joint work with Dani Wise and builds on his earlier work. Let M be a compact oriented irreducible 3-manifold which is neither a graph manifold nor a hyperbolic manifold. We prove that the fundamental group of M is virtually special. This means that it virtually embeds in a right angled Artin group, and is in particular linear over Z. | |||
