  Our understanding of correlated electron systems is vexed by the complexity
of their interactions. Heavy fermion compounds are archetypal examples of this
physics, leading to exotic properties that weave together magnetism,
superconductivity and strange metal behavior. The Kondo semimetal CeSb is an
unusual example where different channels of interaction not only coexist, but
their physical signatures are coincident, leading to decades of debate about
the microscopic picture describing the interactions between the $f$ moments and
the itinerant electron sea. Using angle-resolved photoemission spectroscopy, we
resonantly enhance the response of the Ce$f$-electrons across the magnetic
transitions of CeSb and find there are two distinct modes of interaction that
are simultaneously active, but on different kinds of carriers. This study is a
direct visualization of how correlated systems can reconcile the coexistence of
different modes on interaction - by separating their action in momentum space,
they allow their coexistence in real space.
