Query: Smoothness and Poisson structures of Bridgeland moduli spaces on Poisson
  surfaces   Let X be a projective smooth holomorphic Poisson surface, in other words,
whose anti-canonical divisor is effective. We show that moduli spaces of
certain Bridgeland stable objects on X are smooth. Moreover, we construct
Poisson structures on these moduli spaces.
