Query: Twisted conjugacy and quasi-isometric rigidity of irreducible lattices
  in semisimple Lie groups   Let $G$ be a non-compact semisimple Lie group with finite centre and finitely
many components. We show that any finitely generated group $\Gamma$ which is
quasi-isometric to an irreducible lattice in $G$ has the $R_\infty$-property,
namely, that there are infinitely $\phi$-twisted conjugacy classes for every
automorphism $\phi$ of $\Gamma$. Also, we show that any lattice in $G$ has the
$R_\infty$-property, extending our earlier result for irreducible lattices.
