AbstractGiven an algebraic stack with quasiaffine diagonal, we show that each Gm-gerbe comes from a central separable algebra. In other words, Taylor's bigger Brauer group equals the étale cohomology in degree two with coefficients in Gm. This gives new results also for schemes. We use the method of twisted sheaves explored by Lieblich and de Jong
