  A body placed in a rigidly-rotating fluid becomes circumscribed by a
fictitious cylinder with generators parallel to the axis of rotation, a Taylor
column. Slowly-moving liquid impinging on the body will swerve around the
cylinder. Thus, Taylor columns may form when a breeze impinges on a mountain or
when slowly-moving oceanic water impinges on a seamount, both due to the
Earth's rotation. Here we show that classical non-rotating liquids endowed with
an odd or Hall coefficient of viscosity, exhibiting nondissipative behavior,
also give rise to Taylor column structures resembling halos or spears. Steady
three-dimensional flow of such a liquid becomes effectively two dimensional,
swirling around the Taylor column imitating its rigidly-rotating counterparts.
Formation of Taylor halos and spears is attributed to the propagation of data
along characteristics that may be parallel or oblique to a center axis,
respectively.
