Planck 2018 results. IV. Diffuse component separation

Planck Collaboration, Y. Akrami, M. Ashdown +150

We present full-sky maps of the cosmic microwave background (CMB) and polarized synchrotron and thermal dust emission, derived from the third set of Planck frequency maps. These pr…

CHEX-MATE: The Impact of Triaxiality and Orientation on Planck SZ Cluster Selection and Weak Lensing Mass Measurements

H. Saxena, J. Sayers, A. Gavidia +17

Galaxy cluster abundance measurements are a valuable tool for constraining cosmological parameters like the mass density () and density fluctuation amplitude (). Wide a…

Euclid preparation. First investigation of the impact of cross-contamination on spectroscopic redshift measurements with pixel-level simulations

Euclid Collaboration, F. Passalacqua, S. Anselmi +299

We present a study on simulated data focused on understanding the performance of the spectroscopic redshift measurements with the Near-Infrared Spectrometer and Photometer (NISP) i…

Prospects for Fundamental Physics with LISA

Enrico Barausse, Emanuele Berti, Thomas Hertog +318

In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…

Planck 2018 results. IX. Constraints on primordial non-Gaussianity

Planck Collaboration, Y. Akrami, F. Arroja +157

We analyse the Planck full-mission cosmic microwave background (CMB) temperature and E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We compare e…

Euclid preparation. CosmoPostProcess: A simulation calibrated framework for weak lensing selection bias in richness-selected galaxy clusters

Euclid Collaboration, R. Ingrao, S. Borgani +280

We present \texttt{CosmoPostProcess}, a simulation-based forward-modelling algorithm calibrated to reproduce Euclid optical cluster observables. Its main deliverable is a correctio…

CHEX-MATE: Multi-probe analysis of Abell 1689

L. Chappuis, D. Eckert, M. Sereno +25

The nature of the elusive dark matter can be probed by comparing the predictions of the cold dark matter framework with the gravitational field of massive galaxy clusters. However,…

CHEX-MATE: towards a consistent universal pressure profile and cluster mass reconstruction

M. Muñoz-Echeverría, E. Pointecouteau, G. W. Pratt +31

In a self-similar paradigm of structure formation, the thermal pressure of the hot intra-cluster gas follows a universal distribution once the profile of each cluster is normalised…

Euclid. I. Overview of the Euclid mission

Euclid Collaboration, Y. Mellier, Abdurro'uf +1134

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…

CHEX-MATE: Relationship between X-ray and millimetre inferences of galaxy cluster temperature profiles

F. De Luca, H. Bourdin, P. Mazzotta +25

Thermodynamic profiles from X-ray and millimetre observations of galaxy clusters are often compared under the simplifying assumptions of smooth, spherically symmetric intracluster…

Exploring Cosmic Origins with CORE: Survey requirements and mission design

J. Delabrouille, P. de Bernardis, F. R. Bouchet +200

Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this p…

Euclid preparation. The impact of redshift interlopers on the two-point correlation function analysis

Euclid Collaboration, I. Risso, A. Veropalumbo +317

The Euclid survey aims to measure the spectroscopic redshift of emission-line galaxies by identifying the H line in their slitless spectra. This method is sensitive to the si…

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…
