Using cosmic voids to distinguish f(R) gravity in future galaxy surveys
Paul Zivick, P. M. Sutter, Benjamin D. Wandelt +2
We use properties of void populations identified in -body simulations to forecast the ability of upcoming galaxy surveys to differentiate models of f(R) gravity from \lcdm~cosmo…
Distinguishing f(R) gravity with cosmic voids
Paul Zivick, P. M. Sutter
We use properties of void populations identified in N-body simulations to forecast the ability of upcoming galaxy surveys to differentiate models of f(R) gravity from ΛCDM cosmolog…
Adding Context to JWST Surveys with Current and Future 21cm Radio Observations
Adam P. Beardsley, Miguel F. Morales, Adam Lidz +2
Infrared and radio observations of the Epoch of Reionization promise to revolutionize our understanding of the cosmic dawn, and major efforts with the JWST, MWA and HERA are underw…
Dark matter voids in the SDSS galaxy survey
Florent Leclercq, Jens Jasche, P. M. Sutter +2
What do we know about voids in the dark matter distribution given the Sloan Digital Sky Survey (SDSS) and assuming the model? Recent application of the Bayesian inf…
Modeling cosmic void statistics
Nico Hamaus, P. M. Sutter, Benjamin D. Wandelt
Understanding the internal structure and spatial distribution of cosmic voids is crucial when considering them as probes of cosmology. We present recent advances in modeling void d…
Answers from the void: VIDE and its applications
P. M. Sutter, N. Hamaus, A. Pisani +2
We discuss various applications of VIDE, the Void IDentification and Examination toolkit, an open-source Python/C++ code for finding cosmic voids in galaxy redshift surveys and N-b…
Using hybrid GPU/CPU kernel splitting to accelerate spherical convolutions
P. M. Sutter, Benjamin D. Wandelt, Franz Elsner
We present a general method for accelerating by more than an order of magnitude the convolution of pixelated functions on the sphere with a radially-symmetric kernel. Our method sp…
Testing cosmic geometry without dynamic distortions using voids
Nico Hamaus, P. M. Sutter, Guilhem Lavaux +1
We propose a novel technique to probe the expansion history of the Universe based on the clustering statistics of cosmic voids. In particular, we compute their two-point statistics…
Cosmological parameter constraints from CMB lensing with cosmic voids
Teeraparb Chantavat, Utane Sawangwit, P. M. Sutter +1
We investigate the potential of using cosmic voids as a probe to constrain cosmological parameters through the gravitational lensing effect of the cosmic microwave background (CMB)…
Simulation of the analysis of interferometric microwave background polarization data
Emory F. Bunn, Ata Karakci, Paul M. Sutter +4
We present results from an end-to-end simulation pipeline interferometric observations of cosmic microwave background polarization. We use both maximum-likelihood and Gibbs samplin…
Dark Sky Simulations: Early Data Release
Samuel W. Skillman, Michael S. Warren, Matthew J. Turk +3
The Dark Sky Simulations are an ongoing series of cosmological N-body simulations designed to provide a quantitative and accessible model of the evolution of the large-scale Univer…
VIDE: The Void IDentification and Examination toolkit
P. M. Sutter, Guilhem Lavaux, Nico Hamaus +7
We present VIDE, the Void IDentification and Examination toolkit, an open-source Python/C++ code for finding cosmic voids in galaxy redshift surveys and N-body simulations, charact…
On the observability of coupled dark energy with cosmic voids
P. M. Sutter, Edoardo Carlesi, Benjamin D. Wandelt +1
Taking N-body simulations with volumes and particle densities tuned to match the SDSS DR7 spectroscopic main sample, we assess the ability of current void catalogs (e.g., Sutter et…
A measurement of the Alcock-Paczynski effect using cosmic voids in the SDSS
P. M. Sutter, Alice Pisani, Benjamin D. Wandelt +1
We perform an Alcock-Paczynski test using stacked cosmic voids identified in the SDSS Data Release 7 main sample and Data Release 10 LOWZ and CMASS samples. We find ~1,500 voids ou…
The life and death of cosmic voids
P. M. Sutter, Pascal Elahi, Bridget Falck +5
We investigate the formation, growth, merger history, movement, and destruction of cosmic voids detected via the watershed transform code VIDE in a cosmological N-body dark matter…
Universal Density Profile for Cosmic Voids
Nico Hamaus, P. M. Sutter, Benjamin D. Wandelt
We present a simple empirical function for the average density profile of cosmic voids, identified via the watershed technique in CDM N-body simulations. This function is univer…
