Cosmicflows-3: Two DistanceVelocity Calculators
Ehsan Kourkchi, Helene M. Courtois, Romain Graziani +4
Tools are provided at the Extragalactic Distance Database website that provide relationships between the distances and velocities of galaxies based on smoothed versions of the velo…
XXL Survey groups and clusters in the Hyper Suprime-Cam Survey. Scaling relations between X-ray properties and weak lensing mass
Mauro Sereno, Keiichi Umetsu, Stefano Ettori +13
Scaling relations trace the formation and evolution of galaxy clusters. We exploited multi-wavelength surveys -- the XXL survey at \emph{XMM-Newton} in the X-ray band, and the Hype…
NIKA: a mm camera for Sunyaev-Zel'dovich science in clusters of galaxies
J. F. Macías-Pérez, R. Adam, P. Ade +42
Clusters of galaxies, the largest bound objects in the Universe, constitute a cosmological probe of choice, which is sensitive to both dark matter and dark energy. Within this fram…
Mapping the gas thermodynamic properties of the massive cluster merger MOO J11421527 at z = 1.2
F. Ruppin, R. Adam, P. Ade +51
We present the results of the analysis of the very massive cluster MOO J11421527 at a redshift based on high angular resolution NIKA2 Sunyaev-Zel'dovich (SZ) and $Chan…
A low-mass galaxy cluster as a test-case study for the NIKA2 SZ Large Program
F. Kéruzoré, R. Adam, P. Ade +42
High-resolution mapping of the hot gas in galaxy clusters is a key tool for cluster-based cosmological analyses. Taking advantage of the NIKA2 millimeter camera operated at the IRA…
Hints, neutrino bounds and WDM constraints from SDSS DR14 Lyman- and Planck full-survey data
Nathalie Palanque-Delabrouille, Christophe Yèche, Nils Schöneberg +4
The Ly- forest 1D flux power spectrum is a powerful probe of several cosmological parameters. Assuming a CDM cosmology including massive neutrinos, we find that the latest SD…
Cluster cosmology with the NIKA2 SZ Large Program
F. Mayet, R. Adam, P. Ade +42
The main limiting factor of cosmological analyses based on thermal Sunyaev-Zel'dovich (SZ) cluster statistics comes from the bias and systematic uncertainties that affect the estim…
Theoretical priors in scalar-tensor cosmologies: Thawing quintessence
Carlos García-García, Emilio Bellini, Pedro G. Ferreira +2
The late time acceleration of the Universe can be characterized in terms of an extra, time dependent, component of the universe -- dark energy. The simplest proposal for dark energ…
From diffuse extragalactic and galactic gamma rays to limits on extra dimensions
Michel Cassé, Bruno Mansoulié, Joseph Silk
We derive the maximum fraction of energy emitted in the form of massive (Kaluza- Klein) gravitons by core collapse supernovae, and the corresponding minimal extra-dimensional Planc…
Euclid preparation: VII. Forecast validation for Euclid cosmological probes
Euclid Collaboration, A. Blanchard, S. Camera +151
The Euclid space telescope will measure the shapes and redshifts of galaxies to reconstruct the expansion history of the Universe and the growth of cosmic structures. Estimation of…
-evolution: a relativistic N-body code for clustering dark energy
Farbod Hassani, Julian Adamek, Martin Kunz +1
We introduce -evolution, a relativistic -body code based on , which includes clustering dark energy among its cosmological components. To describe dark e…
New Horizons in Cosmology with Spectral Distortions of the Cosmic Microwave Background
J. Chluba, M. H. Abitbol, N. Aghanim +27
Voyage 2050 White Paper highlighting the unique science opportunities using spectral distortions of the cosmic microwave background (CMB). CMB spectral distortions probe many proce…
Microwave Spectro-Polarimetry of Matter and Radiation across Space and Time
Jacques Delabrouille, Maximilian H. Abitbol, Nabila Aghanim +77
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-di…
Consistency relations for large-scale structure in modified gravity and the matter bispectrum
Marco Crisostomi, Matthew Lewandowski, Filippo Vernizzi
We study perturbation theory for large-scale structure in the most general scalar-tensor theories propagating a single scalar degree of freedom, which include Horndeski theories an…
CMB Spectral Distortions: Status and Prospects
A. Kogut, M. H. Abitbol, J. Chluba +5
Departures of the energy spectrum of the cosmic microwave background (CMB) from a perfect blackbody probe a fundamental property of the universe -- its thermal history. Current upp…
Testing modified gravity at cosmological distances with LISA standard sirens
E. Belgacem, G. Calcagni, M. Crisostomi +18
Modifications of General Relativity leave their imprint both on the cosmic expansion history through a non-trivial dark energy equation of state, and on the evolution of cosmologic…
-attractor dark energy in view of next-generation cosmological surveys
Carlos García-García, Pilar Ruíz-Lapuente, David Alonso +1
The -attractor inflationary models are nowadays favored by CMB Planck observations. Their similarity with canonical quintessence models motivates the exploration of a common fra…
The XXL Survey: XXXVIII. Scatters and correlations of X-ray proxies in the bright XXL cluster sample
Mauro Sereno, Stefano Ettori, Dominique Eckert +5
Context. Scaling relations between cluster properties embody the formation and evolution of cosmic structure. Intrinsic scatters and correlations between X-ray properties are deter…
Integral constraints in spectroscopic surveys
Arnaud de Mattia, Vanina Ruhlmann-Kleider
Clustering analyses of spectroscopic surveys are based upon density fluctuations, which are estimated by comparing the observed tracer density field to a selection function account…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
