Welcome to the CAVITY project!

A full view of galaxies that inhabit voids

The Calar Alto Void Integral-field Treasury surveY, CAVITY, is a legacy project of the Calar Alto Observatory for the coming years. It will generate the first statistically complete data set of galaxies in voids exploring the mass assembly, dark and baryonic, and gas properties of galaxies inhabiting these very low density regions (Perez et al. 2024).

Void galaxies are size and color coded according to their diameter and redshift, respectively. The background small white dots represent the galaxies within the Large Scale Structure of the universe in the redshift range 0.025-0.030, as traced by the Sloan Digital Sky Survey.
