Properties of simulated galaxies and supermassive black holes in cosmic voids

Understand

Cosmic voids, the under-dense regions of the cosmic web, are widely used to constrain cosmology.

• Voids contain few, isolated galaxies, presumably expected to be less evolved and preserving memory of the pristine Universe.
• We use the cosmological hydrodynamical simulation Horizon-AGN coupled to the void finder {\sc \texttt{VIDE}} to investigate properties of galaxies in voids at z=0.
• We find that, closer to void centers, low-mass galaxies are more common than their massive counterparts.
