Euclid preparation. XXV. The Euclid Morphology Challenge -- Towards model-fitting photometry for billions of galaxies
Euclid Collaboration, E. Merlin, M. Castellano +218
The ESA Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real…
Cluster counts III. CDM extensions and the cluster tension
Ziad Sakr, Stephane Ilic, Alain Blanchard
In this work, we examine whether further extensions to the CDM model could alleviate the tension. For that, we derive constraints on the parameters subject of the discrepa…
Euclid preparation: XI. Mean redshift determination from galaxy redshift probabilities for cosmic shear tomography
Euclid Collaboration, O. Ilbert, S. de la Torre +162
The analysis of weak gravitational lensing in wide-field imaging surveys is considered to be a major cosmological probe of dark energy. Our capacity to constrain the dark energy eq…
Euclid: impact of nonlinear prescriptions on cosmological parameter estimation from weak lensing cosmic shear
M. Martinelli, I. Tutusaus, M. Archidiacono +91
Upcoming surveys will map the growth of large-scale structure with unprecented precision, improving our understanding of the dark sector of the Universe. Unfortunately, much of the…
Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
Can the CIB constrain the dark energy?
A. S. Maniyar, G. Lagache, M. Béthermin +1
Galaxies are often used as tracers of the large scale structure (LSS) to measure the Integrated Sachs-Wolfe effect (ISW) by cross-correlating the galaxy survey maps with the Cosmic…
The Dark Matter equation of state through cosmic history
Michael Kopp, Constantinos Skordis, Daniel B. Thomas +1
Cold Dark Matter (CDM) is a crucial constituent of the current concordance cosmological model. Having a vanishing equation of state (EoS), its energy density scales with the invers…
Planck intermediate results. XLVI. Reduction of large-scale systematic effects in HFI polarization maps and estimation of the reionization optical depth
Planck Collaboration, N. Aghanim, M. Ashdown +170
This paper describes the identification, modelling, and removal of previously unexplained systematic effects in the polarization data of the Planck High Frequency Instrument (HFI)…
X-ray galaxy clusters abundance and mass temperature scaling
Stéphane Ilic, Alain Blanchard, Marian Douspis
The abundance of clusters of galaxies is known to be a potential source of cosmological constraints through their mass function. In the present work, we examine the information tha…
Planck 2015 results. XXI. The integrated Sachs-Wolfe effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +229
This paper presents a study of the ISW effect from the Planck 2015 temperature and polarization data release. The CMB is cross-correlated with different LSS tracers: the NVSS, SDSS…
Planck 2013 results. XIX. The integrated Sachs-Wolfe effect
Planck Collaboration, P. A. R. Ade, N. Aghanim +245
Based on CMB maps from the 2013 Planck Mission data release, this paper presents the detection of the ISW effect, i.e., the correlation between the CMB and large-scale evolving gra…
Cosmic Microwave and Infrared Backgrounds cross-correlation for ISW detection
Stéphane Ilic
We investigate the cross-correlation between the cosmic infrared and microwave backgrounds (CIB & CMB) anisotropies through the integrated Sachs-Wolfe effect. We first describe the…
A dark energy view of inflation
Stéphane Ilic, Martin Kunz, Andrew R. Liddle +1
Traditionally, inflationary models are analyzed in terms of parameters such as the scalar spectral index ns and the tensor to scalar ratio r, while dark energy models are studied i…
