The Distribution of Bubble Sizes During Reionization
Yin Lin, S. Peng Oh, Steven R. Furlanetto +1
A key physical quantity during reionization is the size of HII regions. Previous studies found a characteristic bubble size which increases rapidly during reionization, with appare…
Probing cosmology and gravity with redshift-space distortions around voids
Nico Hamaus, P. M. Sutter, Guilhem Lavaux +1
Cosmic voids in the large-scale structure of the Universe affect the peculiar motions of objects in their vicinity. Although these motions are difficult to observe directly, the cl…
Mastering the effects of peculiar velocities in cosmic voids
Alice Pisani, P. M. Sutter, B. D. Wandelt
How do peculiar velocities affect observed voids? To answer this question we use the VIDE toolkit to identify voids in mock galaxy populations embedded within an N-body simulation…
Voids in massive neutrino cosmologies
Elena Massara, Francisco Villaescusa-Navarro, Matteo Viel +1
Cosmic voids are a promising environment to characterize neutrino-induced effects on the large-scale distribution of matter in the universe. We perform a comprehensive numerical st…
Bayesian semi-blind component separation for foreground removal in interferometric 21-cm observations
Le Zhang, Emory F. Bunn, Ata Karakci +5
We present in this paper a new Bayesian semi-blind approach for foreground removal in observations of the 21-cm signal with interferometers. The technique, which we call HIEMICA (H…
Counting voids to probe dark energy
Alice Pisani, P. M. Sutter, Nico Hamaus +4
We show that the number of observed voids in galaxy redshift surveys is a sensitive function of the equation of state of dark energy. Using the Fisher matrix formalism we find the…
Planck 2015 results. XVII. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +239
The Planck full mission cosmic microwave background(CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity(NG). Using three…
