A survey of lens spaces and large-scale CMB anisotropy
  The cosmic microwave background (CMB) anisotropy possesses the remarkable
property that its power is strongly suppressed on large angular scales. This
observational fact can naturally be explained by cosmological models with a
non-trivial topology. The paper focuses on lens spaces L(p,q) which are
realised by a tessellation of the spherical 3-space S^3 by cyclic deck groups
of order p<=72. The investigated cosmological parameter space covers the
interval Omega_tot \in [1.001,1.05]. Several spaces are found which have CMB
correlations on angular scales theta >= 60^\circ suppressed by a factor of two
compared to the simply connected S^3 space. The analysis is based on the S
statistics, and a comparison to the WMAP 7yr data is carried out. Although the
CMB suppression is less pronounced than in the Poincare dodecahedral space,
these lens spaces provide an alternative worth for follow-up studies.
