Efficient Wiener filtering without preconditioning
Franz Elsner, Benjamin D. Wandelt
We present a new approach to calculate the Wiener filter solution of general data sets. It is trivial to implement, flexible, numerically absolutely stable, and guaranteed to conve…
Evolution of isolated overdensities as a control on cosmological N body simulations
Michael Joyce, Francesco Sylos Labini
Beyond convergence studies and comparison of different codes, there are essentially no controls on the accuracy in the non-linear regime of cosmological N body simulations, even in…
Robust, data-driven inference in non-linear cosmostatistics
Benjamin D. Wandelt, Jens Jasche, Guilhem Lavaux
We discuss two projects in non-linear cosmostatistics applicable to very large surveys of galaxies. The first is a Bayesian reconstruction of galaxy redshifts and their number dens…
The expansion of the universe observed with supernovae
Pierre Astier
Over the last 20 years, supernovae have become a key tool to constrain the expansion history of the Universe through the construction of Hubble diagrams, using luminosity distances…
Baryon Acoustic Oscillations in the Ly-α forest of BOSS quasars
Nicolás G. Busca, Timothée Delubac, James Rich +59
We report a detection of the baryon acoustic oscillation (BAO) feature in the three-dimensional correlation function of the transmitted flux fraction in the \Lya forest of high-red…
Will Nonlinear Peculiar Velocity and Inhomogeneous Reionization Spoil 21cm Cosmology from the Epoch of Reionization?
Paul R. Shapiro, Yi Mao, Ilian T. Iliev +4
The 21cm background from the epoch of reionization is a promising cosmological probe: line-of-sight velocity fluctuations distort redshift, so brightness fluctuations in Fourier sp…
CALIFA, the Calar Alto Legacy Integral Field Area survey. II. First public data release
CALIFA collaboration, B. Husemann, K. Jahnke +74
We present the first public data release of the CALIFA survey. It consists of science-grade optical datacubes for the first 100 of eventually 600 nearby (0.005<z<0.03) galaxies, ob…
Luminosity Function from dedicated SDSS-III and MMT data of quasars in 0.7<z<4.0 selected with a new approach
N. Palanque-Delabrouille, Ch. Magneville, Ch. Yeche +25
We present a measurement of the quasar luminosity function in the range 0.68<z<4 down to extinction corrected magnitude g_dered=22.5, using a simple and well understood target sele…
Bayesian Inference of Polarized CMB Power Spectra from Interferometric Data
Ata Karakci, P. M. Sutter, Le Zhang +5
Detection of B-mode polarization of the cosmic microwave background (CMB) radiation is one of the frontiers of observational cosmology. Because they are an order of magnitude faint…
Planck intermediate results. VI: The dynamical structure of PLCKG214.6+37.0, a Planck discovered triple system of galaxy clusters
Planck Collaboration, P. A. R. Ade, N. Aghanim +200
The survey of galaxy clusters performed by Planck through the Sunyaev-Zeldovich effect has already discovered many interesting objects, thanks to the whole coverage of the sky. One…
Compact Groups of Galaxies selected by stellar mass: The 2MASS Compact Group Catalogue
E. Diaz-Gimenez, G. A. Mamon, M. Pacheco +2
We present a photometric catalogue of compact groups of galaxies (p2MCGs) automatically extracted from the 2MASS extended source catalogue. A total of 262 p2MCGs are identified, fo…
Redshifts, Sample Purity, and BCG Positions for the Galaxy Cluster Catalog from the first 720 Square Degrees of the South Pole Telescope Survey
J. Song, A. Zenteno, B. Stalder +74
We present the results of the ground- and space-based optical and near-infrared (NIR) follow-up of 224 galaxy cluster candidates detected with the Sunyaev-Zel'dovich (SZ) effect in…
Planck Intermediate Results. V. Pressure profiles of galaxy clusters from the Sunyaev-Zeldovich effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +214
Taking advantage of the all-sky coverage and broad frequency range of the Planck satellite, we study the Sunyaev-Zeldovich (SZ) and pressure profiles of 62 nearby massive clusters…
The Current Status of Galaxy Formation
Joe Silk, Gary A. Mamon
Understanding galaxy formation is one of the most pressing issues in cosmology. We review the current status of galaxy formation from both an observational and a theoretical perspe…
Physical properties underlying observed kinematics of satellite galaxies
Radoslaw Wojtak, Gary A. Mamon
We study the kinematics of satellites around isolated galaxies selected from the Sloan Digital Sky Survey (SDSS) spectroscopic catalog. Using a model of the phase-space density pre…
Optical/near-infrared selection of red QSOs: Evidence for steep extinction curves towards galactic centers?
J. P. U. Fynbo, J. -K. Krogager, B. Venemans +5
We present the results of a search for red QSOs using a selection based on optical imaging from SDSS and near-infrared imaging from UKIDSS. For a sample of 58 candidates 46 (79%) a…
Supernovae and their host galaxies. I. The SDSS DR8 database and statistics
A. A. Hakobyan, V. Zh. Adibekyan, L. S. Aramyan +5
(Abridged) In this first paper of a series, we report the creation of large and well-defined database that combines extensive new measurements and a literature search of 3876 super…
Late time anisotropy as an imprint of cosmological backreaction
Giovanni Marozzi, Jean-Philippe Uzan
Backreaction effects of the large scale structure on the background dynamics have been claimed to lead to a renormalization of the background dynamics that may account for the late…
Likelihood, Fisher information, and systematics of cosmic microwave background experiments
Franz Elsner, Benjamin D. Wandelt
Every experiment is affected by systematic effects that hamper the data analysis and have the potential to ultimately degrade its performance. In the case of probes of the cosmic m…
Non-Gaussian structure of the lensed CMB power spectra covariance matrix
Aurélien Benoit-Lévy, Kendrick M. Smith, Wayne Hu
Gravitational lensing of the Cosmic Microwave Background (CMB) encodes cosmological information in the observed anisotropies of temperature and polarization. Accurate extraction of…
