CD Kreisch, A Pisani, C Carbone, J Liu… - Monthly Notices of …, 2019 - academic.oup.com
Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As
we vary the sum of the neutrino masses, we find void statistics contain information absent …

Beyond BAO: Improving cosmological constraints from BOSS data with measurement of the void-galaxy cross-correlation

S Nadathur, PM Carter, WJ Percival, HA Winther… - Physical Review D, 2019 - APS
We present a measurement of the anisotropic void-galaxy cross-correlation function in the
CMASS galaxy sample of the BOSS DR12 data release. We perform a joint fit to the data for …

Cosmological constraints from the BOSS DR12 void size function

The apparent shape of galaxy clustering depends on the adopted cosmology used to
convert observed redshift to comoving distance, the r (z) relation, as it changes the line …

The bias of cosmic voids in the presence of massive neutrinos

N Schuster, N Hamaus, A Pisani… - … of Cosmology and …, 2019 - iopscience.iop.org
Cosmic voids offer an extraordinary opportunity to study the effects of massive neutrinos on
cosmological scales. Because they are freely streaming, neutrinos can penetrate the interior …
