The HANDY model with non-renewable resources and societal effects
Mathilde Badoual, Basil Grammaticos, Stéphane Plaszczynski +1
We present an extension of the single-population Human and Nature Dynamics (HANDY) model that explicitly incorporates non-renewable resources and societal effects. The model is for…
A stochastic model of discussion
S. Plaszczynski, B. Grammaticos, M. Badoual
We consider the duration of discussions in face-to-face contacts and propose a stochastic model to describe it. It is based on the points of a Levy flight where the duration of eac…
On the duration of face-to-face contacts
Stephane Plaszczynski, Gilberto Nakamura, Basile Grammaticos +1
The analysis of social networks, in particular those describing face-to-face interactions between individuals, is complex due to the intertwining of the topological and temporal as…
Cosmological constraints on the neutrino mass including systematic uncertainties
F. Couchot, S. Henrot-Versillé, O. Perdereau +4
When combining cosmological and oscillations results to constrain the neutrino sector, the question of the propagation of systematic uncertainties is often raised. We address this…
Angpow: a software for the fast computation of accurate tomographic power spectra
J. -E. Campagne, J. Neveu, S. Plaszczynski
The statistical distribution of galaxies is a powerful probe to constrain cosmological models and gravity. In particular the matter power spectrum brings information about t…
Planck intermediate results. XLIV. The structure of the Galactic magnetic field from dust polarization maps of the southern Galactic cap
Planck Collaboration, N. Aghanim, M. I. R. Alves +165
We study the statistical properties of interstellar dust polarization at high Galactic latitude, using the Stokes parameter Planck maps at 353 GHz. Our aim is to advance the unders…
Relieving tensions related to the lensing of CMB temperature power spectra
F. Couchot, S. Henrot-Versillé, O. Perdereau +4
The angular power spectra of the cosmic microwave background (CMB) temperature anisotropies reconstructed from Planck data seem to present too much gravitational lensing distortion…
Planck 2015 results. XXIII. The thermal Sunyaev-Zeldovich effect--cosmic infrared background correlation
Planck Collaboration, P. A. R. Ade, N. Aghanim +199
We use Planck data to detect the cross-correlation between the thermal Sunyaev-Zeldovich (tSZ) effect and the infrared emission from the galaxies that make up the the cosmic infrar…
Planck 2013 results. XXXI. Consistency of the Planck data
Planck Collaboration, P. A. R. Ade, M. Arnaud +180
The Planck design and scanning strategy provide many levels of redundancy that can be exploited to provide tests of internal consistency. One of the most important is the compariso…
Planck 2015 results. XXVI. The Second Planck Catalogue of Compact Sources
Planck Collaboration, P. A. R. Ade, N. Aghanim +240
The Second Planck Catalogue of Compact Sources is a catalogue of sources detected in single-frequency maps from the full duration of the Planck mission and supersedes previous vers…
Optimized Large-Scale CMB Likelihood And Quadratic Maximum Likelihood Power Spectrum Estimation
E. Gjerløw, L. P. L. Colombo, H. K. Eriksen +5
We revisit the problem of exact CMB likelihood and power spectrum estimation with the goal of minimizing computational cost through linear compression. This idea was originally pro…
Planck 2015 results. XVII. Constraints on primordial non-Gaussianity
Planck Collaboration, P. A. R. Ade, N. Aghanim +239
The Planck full mission cosmic microwave background(CMB) temperature and E-mode polarization maps are analysed to obtain constraints on primordial non-Gaussianity(NG). Using three…
Planck 2015 results. XIV. Dark energy and modified gravity
Planck Collaboration, P. A. R. Ade, N. Aghanim +232
We study the implications of Planck data for models of dark energy (DE) and modified gravity (MG), beyond the cosmological constant scenario. We start with cases where the DE only…
A Joint Analysis of BICEP2/Keck Array and Planck Data
BICEP2/Keck, Planck Collaborations, : +276
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400 deg patch of sky centered on…
Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes
Planck Collaboration, R. Adam, P. A. R. Ade +230
The polarized thermal emission from Galactic dust is the main foreground present in measurements of the polarization of the cosmic microwave background (CMB) at frequencies above 1…
Polarization measurements analysis I. Impact of the full covariance matrix on polarization fraction and angle measurements
L. Montier, S. Plaszczynski, F. Levrier +4
With the forthcoming release of high precision polarization measurements, such as from the Planck satellite, the metrology of polarization needs to improve. In particular, it is cr…
A novel estimator of the polarization amplitude from normally distributed Stokes parameters
S. Plaszczynski, L. Montier, F. Levrier +1
We propose a novel estimator of the polarization amplitude from a single measurement of its normally distributed Stokes components. Based on the properties of the Rice dist…
Planck 2013 results. XVII. Gravitational lensing by large-scale structure
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
On the arcminute angular scales probed by Planck, the CMB anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this effect, detecting len…
A hybrid approach to CMB lensing reconstruction on all-sky intensity maps
S. Plaszczynski, A. Lavabre, L. Perotto +1
Based on realistic simulations, we propose an hybrid method to reconstruct the lensing potential power spectrum, directly on PLANCK-like CMB frequency maps. It implies using a larg…
