Query: Bounds on Isocurvature Perturbations from CMB and LSS   Using both cosmic microwave background and large scale structure data, we put
stringent bounds on the possible cold dark matter, baryon and neutrino
isocurvature contributions to primordial fluctuations in the Universe.
Neglecting the possible effects of spatial curvature, tensor perturbations and
reionization, we perform a Bayesian likelihood analysis with nine free
parameters, and find that the relative amplitude of the isocurvature component
cannot be larger than about a few percent for uncorrelated models. On the other
hand, for correlated adiabatic and isocurvature components, the ratio could be
slightly larger. However, the cross-correlation coefficient is strongly
constrained, and maximally correlated/anticorrelated models are disfavored.
