  We use the SIMBA galaxy formation simulation suite to explore anisotropies in
the properties of circumgalactic gas that result from accretion and feedback
processes. We particularly focus on the impact of bipolar active galactic
nuclei (AGN) jet feedback as implemented in SIMBA, which quenches galaxies and
has a dramatic effect on large-scale gas properties. We show that jet feedback
at low redshifts is most common in the stellar mass range $(1-5)\times
10^{10}M_\odot$, so we focus on galaxies with active jets in this mass range.
In comparison to runs without jet feedback, jets cause lower densities and
higher temperatures along the galaxy minor axis (SIMBA jet direction) at radii
>=$0.5r_{200c}-4r_{200c}$ and beyond. This effect is less apparent at higher or
lower stellar masses, and is strongest within green valley galaxies. The
metallicity also shows strong anisotropy out to large scales, driven by star
formation feedback. We find substantially stronger anisotropy at
<=$0.5r_{200c}$, but this also exists in runs with no explicit feedback,
suggesting that it is due to anisotropic accretion. Finally, we explore
anisotropy in the bulk radial motion of the gas, finding that both star
formation and AGN wind feedback contribute to pushing the gas outwards along
the minor axis at <=1 Mpc, but AGN jet feedback further causes bulk outflow
along the minor axis out to several Mpc, which drives quenching via gas
starvation. These results provide observational signatures for the operation of
AGN feedback in galaxy quenching.
