MAGNETIC FIELDS IN INTERSTELLAR CLOUDS FROM ZEEMAN OBSERVATIONS: INFERENCE OF TOTAL FIELD STRENGTHS BY BAYESIAN ANALYSIS
- R. M. Crutcher, B. Wandelt, C. Heiles, E. Falgarone, T. H. Troland
- Physics
- 10 December 2010
The only direct measurements of interstellar magnetic field strengths depend on the Zeeman effect, which samples the line-of-sight component B{sub z} of the magnetic vector. In this paper, we use a… Expand
LSST Science Book, Version 2.0
- L. S. C. P. A. Abell, J. Allison, +242 authors H. Zhan
- Physics, Engineering
- 1 December 2009
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic… Expand
A public void catalog from the SDSS DR7 Galaxy Redshift Surveys based on the watershed transform
- P. Sutter, G. Lavaux, B. Wandelt, D. Weinberg
- Physics
- 11 July 2012
We produce the most comprehensive public void catalog to date using the Sloan Digital Sky Survey Data Release 7 main sample out to redshift z = 0.2 and the luminous red galaxy sample out to z = 0.44.… Expand
Planck 2015 results - XVII. Constraints on primordial non-Gaussianity
- P. C. P. Ade, N. Aghanim, +236 authors A. Zonca
- Physics
- 20 March 2013
The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal bispectrum estimators, separable… Expand
Halo Properties in Cosmological Simulations of Self-Interacting Cold Dark Matter
- R. Dave', D. Spergel, P. Steinhardt, B. Wandelt
- Physics
- 15 June 2000
We present a comparison of halo properties in cosmological simulations of collisionless cold dark matter (CDM) and self-interacting dark matter (SIDM) for a range of dark matter cross sections. We… Expand
Universal density profile for cosmic voids.
- N. Hamaus, P. Sutter, B. Wandelt
- Physics, Medicine
- Physical review letters
- 21 March 2014
We present a simple empirical function for the average density profile of cosmic voids, identified via the watershed technique in ΛCDM N-body simulations. This function is universal across void size… Expand
Evidence of primordial non-Gaussianity (fNL) in the Wilkinson microwave anisotropy probe 3-year data at 2.8sigma.
- A. Yadav, B. Wandelt
- Physics, Medicine
- Physical review letters
- 7 May 2008
We present evidence for primordial non-Gaussianity of the local type (fNL) in the temperature anisotropy of the cosmic microwave background. Analyzing the bispectrum of the Wilkinson Microwave… Expand
A measurement of the Alcock–Paczyński effect using cosmic voids in the SDSS
- P. Sutter, A. Pisani, B. Wandelt, D. Weinberg
- Physics
- 22 April 2014
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 out to redshift $0.6$… Expand

Sparse sampling, galaxy bias, and voids
- P. Sutter, G. Lavaux, N. Hamaus, B. Wandelt, D. Weinberg, M. Warren
- Physics
- 19 September 2013
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 subsampled dark matter, halo… Expand
