The dark matter of galaxy voids
P. M. Sutter, Guilhem Lavaux, Benjamin D. Wandelt +2
How do observed voids relate to the underlying dark matter distribution? To examine the spatial distribution of dark matter contained within voids identified in galaxy surveys, we…
A response to arXiv:1310.2791: A self-consistent public catalogue of voids and superclusters in the SDSS Data Release 7 galaxy surveys
P. M. Sutter, Guilhem Lavaux, Benjamin D. Wandelt +1
Recently, Nadathur & Hotchkiss (2013) submitted a paper discussing a new cosmic void catalog. This paper includes claims about the void catalog described in Sutter et al. (2012). I…
Voids in the SDSS DR9: observations, simulations, and the impact of the survey mask
P. M. Sutter, Guilhem Lavaux, Benjamin D. Wandelt +3
We present and study cosmic voids identified using the watershed void finder VIDE in the Sloan Digital Sky Survey Data Release 9, compare these voids to ones identified in mock cat…
Sparse sampling, galaxy bias, and voids
P. M. Sutter, Guilhem Lavaux, Nico Hamaus +3
To study the impact of sparsity and galaxy bias on void statistics, we use a single large-volume, high-resolution N-body simulation to compare voids in multiple levels of subsample…
First measurement of gravitational lensing by cosmic voids in SDSS
Peter Melchior, P. M. Sutter, Erin S. Sheldon +2
We report the first measurement of the diminutive lensing signal arising from matter underdensities associated with cosmic voids. While undetectable individually, by stacking the w…
Cosmology with Void-Galaxy Correlations
Nico Hamaus, Benjamin D. Wandelt, P. M. Sutter +2
Galaxy bias, the unknown relationship between the clustering of galaxies and the underlying dark matter density field is a major hurdle for cosmological inference from large-scale…
Real-space density profile reconstruction of stacked voids
Alice Pisani, Guilhem Lavaux, Paul M. Sutter +1
We present a non-parametric, model-independent method to reconstruct the spherical density profiles of void stacks in real space, without redshift-space distortions. Our method use…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
Planck 2013 Results. XXIV. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +237
The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal bispectrum estimators, sep…
Systematic Effects in Interferometric Observations of the CMB Polarization
Ata Karakci, Le Zhang, P. M. Sutter +5
The detection of the primordial -mode spectrum of the polarized cosmic microwave background (CMB) signal may provide a probe of inflation. However, observation of such a faint s…
