Cold imprint of supervoids in the Cosmic Microwave Background re-considered with Planck and BOSS DR10

Understand

We analyze publicly available void catalogs of the Baryon Oscillation Spectroscopic Survey Data Release 10 at redshifts $0.4<z<0.7$.

• The first goal of this paper is to extend the Cosmic Microwave Background stacking analysis of previous spectroscopic void samples at $z<0.4$.
• In addition, the DR10 void catalog provides the first chance to spectroscopically probe the volume of the Granett et al.
• (2008) supervoid catalog that constitutes the only set of voids which has shown a significant detection of a cross-correlation signal between void locations and average CMB chill.
