Algebras with separating almost cyclic coherent Auslander-Reiten components

We prove that the class of Artin algebras whose Auslander-Reiten quiver admits a separating family of almost cyclic coherent components coincides with the class of generalized multicoil enlargements of concealed canonical algebras. Moreover, the module category, homological properties and the representation type of Artin algebras with separating families of almost cyclic coherent Auslander-Reiten components are described.
