We slightly extend results of Evens and Mirković and “compute” the characteristic cycles of intersection cohomology sheaves on transversal slices in a double affine Grassmannian. We propose a conjecture relating the hyperbolic stalks and microlocalization at a torus-fixed point in a Poisson variety.
Keywords: vanishing cycles, Poisson varieties, Uhlenbeck spaces, double affine Grassmannian.
