Profinite properties of RAAGs and special groups

In this paper, we prove that right-angled Artin groups (RAAGs) are distinguished from each other by their pro-p completions for any choice of prime p, and that right-angled Coxeter groups (RACGs) are distinguished from each other by their pro-2 completions. We also give a new proof that hyperbolic virtually special groups are good in the sense of Serre. Furthermore, we give an example of a property of the underlying graph of a RAAG that translates to a property of the profinite completion.
