Acylindrical Hyperbolicity Conjecture for irreducible Artin groups

Let $A_\Gamma$ be an irreducible Artin group, and let $Z(A_\Gamma)$ denote its centre. The central quotient is $A_\Gamma/Z(A_\Gamma)$. Acylindrical Hyperbolicity Conjecture. The group

$$A_\Gamma/Z(A_\Gamma)$$

is acylindrically hyperbolic. This describes the expected acylindrical hyperbolicity of Artin groups after removing the obstruction from their centre: reducible groups split as direct products, while spherical-type groups have an infinite cyclic centre. The central-quotient statement is known for spherical-type Artin groups by work of Calvez and Wiest; the conjecture remains unresolved in the stated generality for irreducible Artin groups.
