  Traditionally, the solar magnetic field has been considered to have a
negligible effect in the outer regions of the heliosphere. Recent works have
shown that the solar magnetic field may play a crucial role in collimating the
plasma in the heliosheath. Interstellar Boundary Explorer (IBEX) observations
of the heliotail indicated a latitudinal structure varying with energy in the
energetic neutral atom (ENA) fluxes. At energies ~1 keV, the ENA fluxes show an
enhancement at low latitudes and a deficit of ENAs near the poles. At energies
>2.7 keV, ENA fluxes had a deficit within low latitudes, and lobes of higher
ENA flux near the poles. This ENA structure was initially interpreted to be a
result of the latitudinal profile of the solar wind during solar minimum. We
extend the work of Kornbleuth et al. (2018) by using solar minimum-like
conditions and the recently developed SHIELD model. The SHIELD model couples
the magnetohydrodynamic (MHD) plasma solution with a kinetic description of
neutral hydrogen. We show that while the latitudinal profile of the solar wind
during solar minimum contributes to the lobes in ENA maps, the collimation by
the solar magnetic field is important in creating and shaping the two high
latitude lobes of enhanced ENA flux observed by IBEX. This is the first work to
explore the effect of the changing solar magnetic field strength on ENA maps.
Our findings suggest that IBEX is providing the first observational evidence of
the collimation of the heliosheath plasma by the solar magnetic field.
