Alcock-Paczyński effect on void-finding: Implications for void-galaxy cross-correlation modelling
Slađana Radinović, Hans A. Winther, Seshadri Nadathur +5
Under the assumption of statistical isotropy, and in the absence of directional selection effects, a stack of voids is expected to be spherically symmetric, which makes it an excel…

Modelling the BOSS void-galaxy cross-correlation function using a neural-network emulator
Tristan S. Fraser, Enrique Paillas, Will J. Percival +3
We introduce an emulator-based method to model the cross-correlation between cosmological voids and galaxies. This allows us to model the effect of cosmology on void finding and on…

Cosmological measurements from void-galaxy and galaxy-galaxy clustering in the Sloan Digital Sky Survey
Alex Woodfinden, Will J. Percival, Seshadri Nadathur +5
We present the cosmological implications of measurements of void-galaxy and galaxy-galaxy clustering from the Sloan Digital Sky Survey (SDSS) Main Galaxy Sample (MGS), Baryon Oscil…
