  We study the endomorphism algebra of Verma modules for rational Cherednik
algebras at t=0. It is shown that, in many cases, these endomorphism algebras
are quotients of the centre of the rational Cherednik algebra. Geometrically,
they define Lagrangian subvariaties of the generalized Calogero-Moser space. In
the introduction, we motivate our results by describing them in the context of
derived intersections of Lagrangians.
