Abstract
We prove that every countable family of countable acylindrically hyperbolic groups has a common finitely generated acylindrically hyperbolic quotient. As an application, we obtain an acylindrically hyperbolic group with strong fixed point properties: has property for all , and every action of on a finite dimensional contractible topological space has a fixed point. In addition, has other properties which are rather unusual for groups exhibiting "hyperbolic-like" behaviour. E.g., is not uniformly non-amenable and has finite generating sets with arbitrary large balls consisting of torsion elements.
