CMB dipoles and other low-order multipoles in the quasispherical
  Szekeres model
  Several authors have previously shown that Gpc-scale void based on the
spherically symmetric LTB model can provide a good fit to certain cosmological
data, including the SNIa data, but it is only consistent with the observed CMB
dipole if we are located very close to the center, in violation of the
Copernican principle. In this work we investigate the more general
quasispherical Szekeres model, which does not include spherical symmetry, in
order to determine whether this option may be less constricting. We find that
the observer is still constrained to a small region, but it is not as
geometrically ``special'' as the center of an LTB void. Furthermore, whereas
the quadrupole and octupole near the center of an LTB void are necessarily
small, certain Szekeres models can include a significant quadrupole while still
being consistent with the observed dipole, hinting that Szekeres models may be
able give an explanation for the observed quadrupole/octupole anomalies.
