Query: Intermittence of the Map of Kinetic Sunyaev-Zel'dovich Effect and
  Turbulence of IGM   We investigate the possibility of detecting the turbulent state of the IGM
with the kinetic Sunyaev-Zel'dovich (kSZ) effect. Being sensitive to the
divergence-free component of the momentum field of the IGM, the kSZ effect
might be used to probe the vorticity of the turbulent IGM. With cosmological
hydrodynamical simulation in the concordance $\Lambda$CDM universe, we find
that the structure functions of 2D kSZ maps show strong intermittence, and the
intermittent exponents follow a law similar to the She-Leveque scaling formula
of fully developed turbulence. We also find that the intermittence is weak in
the maps of thermal Sunyaev-Zel'dovich (tSZ) effect. Nevertheless, the
superposition of the kSZ and tSZ effects still contain significant
intermittence. We conclude that the turbulent behavior of the IGM may be
revealed by the observation of SZ effect on angular scales equal to or less
than 0.5 arcminute, corresponding to the multipole parameter $l\geq 2
\times10^4$.
