Resumen:
Cosmic voids, defined as the largest spherical regions with an integrated density of at most a 10\% of the mean density, are of great interest given their relation to the large scale distribution of mass and the way they trace cosmic flows shaping the cosmic web. Also, voids are dynamically evolving entities, and show a synergy with the surrounding overdensities that can be used to describe the growth of structures. Here we show that the distribution of voids has, in consonance with the distribution of mass, a characteristic scale at which void pairs are preferentially separated. This allows to identify clumps of voids with similar environments and use them to define second order underdensities. We also explore the impact of these large underdensities on the cosmic microwave background.
