Effects of Lyman alpha scattering in the IGM on clustering statistics of
  Lyman alpha emitters
  We investigate the correlations between the observed fraction of Lyman alpha
emission from star-forming galaxies and the large scale structure by
post-processing snapshots of a large, high resolution hydrodynamical simulation
with a Lyman alpha radiative transfer code at redshifts z=4, 3, 2. We find
correlations of the observed fraction with density, density gradient along the
line of sight, velocity and velocity gradient along the line of sight, all
within the same order of magnitude (tens of percent). Additionally, a
correlation with the angular momentum of the dark matter halo is detected. In
contrast to a previous study, we find no significant deformation of the 2-point
correlation function due to selection effects from radiative transfer in the
IGM within the limited statistics of the simulation volume.
