Nonlinear velocity power spectrum: modeling the cosmological dependence on the Hubble constant and cold dark matter density
Francesca Lepori, Ruth Durrer, Martin Kunz +3
In this paper we present a semi-analytical model for the velocity power spectrum in $\La$CDM cosmology for wave numbers Mpc. We mainly concentrate on the dominant divergence…
Probing the Cosmological Principle with CMB lensing and cosmic shear
James Adam, Roy Maartens, Julien Larena +2
The standard cosmological model assumes the Cosmological Principle. However, recent observations hint at possible violations of isotropy on large scales, possibly through late-time…
Anchors no more: Using peculiar velocities to constrain and the primordial Universe without calibrators
Davide Piras, Francesco Sorrenti, Ruth Durrer +1
We develop a novel approach to constrain the Hubble parameter and the primordial power spectrum amplitude using type Ia supernovae (SNIa) data. By considering…
Detecting rotation from lensing in the CMB
Julien Carron, Enea di Dio, Ruth Durrer
An excellent estimate of the lensing signal is expected from the availability of deep and high-resolution polarization data in the near future. This is most important to allow for…
An Independent Measure of the Kinematic Dipole from SDSS
Prabhakar Tiwari, Dominik J. Schwarz, Gong-Bo Zhao +3
We utilize the Sloan Digital Sky Survey (SDSS) extended Baryon Oscillation Spectroscopic Survey (eBOSS) and Baryon Oscillation Spectroscopic Survey (BOSS) catalogs with precise spe…
A local infall from a cosmographic analysis of Pantheon+
Francesco Sorrenti, Ruth Durrer, Martin Kunz
We present a model independent analysis of the Pantheon+ supernova sample and study the dependence of the recovered values of , and on the redshift cut and on the…
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…
The low multipoles in the Pantheon+SH0ES data
Francesco Sorrenti, Ruth Durrer, Martin Kunz
In previous work we have shown that the dipole in the low redshift supernovae of the Pantheon+SH0ES data does not agree with the one inferred from the velocity of the solar system…
Fast and spurious: a robust determination of our peculiar velocity with future galaxy surveys
Fabien Lacasa, Camille Bonvin, Charles Dalang +1
To date, the most precise measurement of the observer's peculiar velocity comes from the dipole in the Cosmic Microwave Background (CMB). This velocity also generates a dipole in t…
Towards Cosmography of the Local Universe
Julian Adamek, Chris Clarkson, Ruth Durrer +3
Anisotropies in the distance-redshift relation of cosmological sources are expected due to large-scale inhomogeneities in the local Universe. When the observed sources are tracing…
Euclid Preparation. TBD. Impact of magnification on spectroscopic galaxy clustering
Euclid Collaboration, G. Jelic-Cizmek, F. Sorrenti +226
In this paper we investigate the impact of lensing magnification on the analysis of Euclid's spectroscopic survey, using the multipoles of the 2-point correlation function for gala…
The halo bias for number counts on the light cone from relativistic N-body simulations
Francesca Lepori, Sebastian Schulz, Julian Adamek +1
We present the halo number counts and its two-point statistics, the observable angular power spectrum, extracted for the first time from relativistic N-body simulations. The halo c…
Cosmology and Fundamental Physics with the Euclid Satellite
Luca Amendola, Stephen Appleby, Anastasios Avgoustidis +69
Euclid is a European Space Agency medium class mission selected for launch in 2020 within the Cosmic Vision 2015 2025 program. The main goal of Euclid is to understand the origin o…
Constraining the dynamical dark energy parameters: Planck-2013 vs WMAP9
B. Novosyadlyj, O. Sergijenko, R. Durrer +1
We determine the best-fit values and confidence limits for dynamical dark energy parameters together with other cosmological parameters on the basis of different datasets which inc…
Cosmology and fundamental physics with the Euclid satellite
Luca Amendola, Stephen Appleby, David Bacon +60
Euclid is a European Space Agency medium class mission selected for launch in 2019 within the Cosmic Vision 2015-2025 programme. The main goal of Euclid is to understand the origin…
Testing the paradigm of adiabaticity
R. Trotta, R. Durrer
We introduce the concepts of adiabatic (curvature) and isocurvature (entropy) cosmological perturbations and present their relevance for parameter estimation from cosmic microwave…
