Euclid preparation. XCVIII. Cosmology Likelihood for Observables in Euclid (CLOE). 5: Extensions beyond the standard modelling of theoretical probes and systematic effects
Euclid Collaboration, L. W. K. Goh, A. Nouri-Zonoz +301
Euclid is expected to establish new state-of-the-art constraints on extensions beyond the standard LCDM cosmological model by measuring the positions and shapes of billions of gala…
Geometric Methods for Spherical Data, with Applications to Cosmology
Javier Carrón Duque, Domenico Marinucci
This survey is devoted to recent developments in the statistical analysis of spherical data, with a view to applications in Cosmology. We will start from a brief discussion of Cosm…
Minkowski Functionals in for the spin-2 CMB polarisation field
Javier Carrón Duque, Alessandro Carones, Domenico Marinucci +2
The study of the angular power spectrum of Cosmic Microwave Background (CMB) anisotropies, both in intensity and in polarisation, has led to the tightest constraints on cosmologica…
Multi-Clustering Needlet-ILC for CMB B-modes component separation
Alessandro Carones, Marina Migliaccio, Giuseppe Puglisi +4
The Cosmic Microwave Background (CMB) primordial B-modes signal is predicted to be much lower than the polarized Galactic emission (foregrounds) in any region of the sky pointing t…
Analysis of NILC performance on B-modes data of sub-orbital experiments
Alessandro Carones, Marina Migliaccio, Domenico Marinucci +1
The observation of primordial B-modes in the Cosmic Microwave Background (CMB) represents the main scientific goal of most of the future CMB experiments. This signal is predicted t…
A novel Cosmic Filament catalogue from SDSS data
Javier Carrón Duque, Marina Migliaccio, Domenico Marinucci +1
In this work we present a new catalogue of Cosmic Filaments obtained from the latest Sloan Digital Sky Survey (SDSS) public data. In order to detect filaments, we implement a versi…
Needlet thresholding methods in component separation
F. Oppizzi, A. Renzi, M. Liguori +5
Foreground components in the Cosmic Microwave Background (CMB) are sparse in a needlet representation, due to their specific morphological features (anisotropy, non-Gaussianity). T…
Point Source Detection and False Discovery Rate Control on CMB Maps
Javier Carrón Duque, Alessandro Buzzelli, Yabebal Fantaye +3
We discuss a new procedure to search for point sources in Cosmic Microwave background maps; in particular, we aim at controlling the so-called False Discovery Rate, which is define…
The Needlet CMB Trispesctrum
Antonino Troja, Simona Donzelli, Davide Maino +1
We propose a computationally feasible estimator for the needlet trispectrum, which develops earlier work on the bispectrum by Donzelli et al. (2012). Our proposal seems to enjoy a…
Sparse Inpainting and Isotropy
Stephen M. Feeney, Domenico Marinucci, Jason D. McEwen +3
Sparse inpainting techniques are gaining in popularity as a tool for cosmological data analysis, in particular for handling data which present masked regions and missing observatio…
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…
On the linear term correction for needlets/wavelets non-Gaussianity estimators
Simona Donzelli, Frode K. Hansen, Michele Liguori +2
We derive the linear correction term for needlet and wavelet estimators of the bispectrum and the non-linearity parameter fNL on cosmic microwave background radiation data. We show…
Detection of new point sources in WMAP 7 year data using internal templates and needlets
Sandro Scodeller, Frode K. Hansen, Domenico Marinucci
We have developed a new needlet based method to detect point sources in cosmic microwave background (CMB) maps and have applied it to the WMAP 7 year data. We use both the individu…
Directional Variations of the Non-Gaussianity Parameter f_NL
Øystein Rudjord, Frode K. Hansen, Xiaohong Lan +3
We investigate local variations of the primordial non-Gaussianity parameter f_NL in the WMAP data, looking for possible influence of foreground contamination in the full-sky estima…
An Estimate of the Primordial Non-Gaussianity Parameter f_NL Using the Needlet Bispectrum from WMAP
Oystein Rudjord, Frode K. Hansen, Xiaohong Lan +3
We use the full bispectrum of spherical needlets applied to the WMAP data of the cosmic microwave background as an estimator for the primordial non-Gaussianity parameter f_NL. We u…
