Imprints of the cosmic void evolution on the baryon processes inside
  galaxy haloes
  Cosmic voids provide a unique environment to study galaxy formation and
evolution. In this paper, we analyse a set of hydrodynamic zoom-in simulations
of voids, to analyse in detail their inner structures. These voids were
identified in a cosmological simulation and classified according to their
surrounding dynamics at very large scales: whether they are in expansion or
contraction at their outskirts. We study how these environments and the
dynamics of voids impact the baryonic processes inside haloes and their
mechanisms of formation and evolution. We find an under-abundance of processed
gas within the voids that can be associated with the lack of massive haloes. By
studying the dynamical phase-space diagram of haloes and the halo-particle
correlation function, we find that haloes inside of contracting voids are
slightly affected by the presence of bigger structures, in comparison to haloes
in the inner regions of expanding voids. Consistent signals are obtained both
when using dark matter and gas particles. We show that the halo assembly
depends on the void dynamical state: haloes in expanding voids assemble slowly
than those in contracting voids and in the general universe. This difference in
the assembly impacts the baryonic evolution of haloes. Overall the redshift
range analysed, haloes in voids have less baryon content than haloes in the
general universe and particularly at z = 0 less stellar content. Our results
suggest that the large scale void environment modulate the baryonic process
occurring inside haloes according to the void dynamical state.
