Resumen:
We perform a statistical study about properties of galaxiesin underdense regions in the 2dFGRS.We consider galaxies in voids and shells and investigate dependenceswith spectral signatures.We analyze variations in the mean fraction of galaxies with distance to thevoid center. A a result, we find a clear overdensity ofgalaxies with intermediate star formation rateat voids shells and a predominance ofgalaxies with high star formation rate inside voids.
