Query: Local photoionization feedback effects on galaxies   We implement an optically thin approximation for the effects of the local
radiation field from stars and hot gas on the gas heating and cooling in the
N-body SPH code GASOLINE2. We resimulate three galaxies from the NIHAO project:
one dwarf, one Milky Way-like and one massive spiral, and study what are the
local radiation field effects on various galaxy properties. We also study the
effects of varying the Ultra Violet Background (UVB) model, by running the same
galaxies with two different UVBs. Galaxy properties at $z=0$ like stellar mass,
stellar effective mass radius, HI mass, and radial extent of the HI disc, show
significant changes between the models with and without the local radiation
field, and smaller differences between the two UVB models. The intrinsic effect
of the local radiation field through cosmic time is to increase the equilibrium
temperature at the interface between the galaxies and their circumgalactic
media (CGM), moving this boundary inwards, while leaving relatively unchanged
the gas inflow rate. Consequently, the temperature of the inflow increases when
considering the local radiation sources. This temperature increase is a
function of total galaxy mass, with a median CGM temperature difference of one
order of magnitude for the massive spiral. The local radiation field suppresses
the stellar mass growth by $\sim$20 per cent by $z=0$ for all three galaxies,
while the HI mass is roughly halfed. The differences in the gas phase diagrams,
significantly impact the HI column densities, shifting their peaks in the
distributions towards lower $N_{\rm HI}$.
