Cosmic void exclusion models and their impact on the distance scale measurements from large scale structure

Andrei Variu, Cheng Zhao, Daniel Forero-Sánchez +5

Baryonic Acoustic Oscillations (BAOs) studies based on the clustering of voids and matter tracers provide important constraints on cosmological parameters related to the expansion…

Void BAO measurements on quasars from eBOSS

A. Tamone, C. Zhao, D. Forero-Sánchez +5

We present the clustering of voids based on the quasar (QSO) sample of the extended Baryon Oscillation Spectroscopic Survey Data Release 16 in configuration space. We define voids…
