Initial Evaluation of SNEMO2 and SNEMO7 Standardization Derived From Current Light Curves of Type Ia Supernovae
B. M. Rose, S. Dixon, D. Rubin +7
To determine if the SuperNova Empirical Model (SNEMO) can improve Type Ia supernova (SN Ia) standardization of several currently available photometric data sets, we perform an init…
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…
Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
Going deep with Minkowski functionals of convergence maps
Carolina Parroni, Vincenzo F. Cardone, Roberto Maoli +1
Stage IV lensing surveys promise to make available an unprecedented amount of excellent data which will represent a huge leap in terms of both quantity and quality. This will open…
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…
Phase-space structure of cold dark matter halos inside splashback: multi-stream flows and self-similar solution
Hiromu Sugiura, Takahiro Nishimichi, Yann Rasera +1
Using the motion of accreting particles onto halos in cosmological -body simulations, we study the radial phase-space structures of cold dark matter (CDM) halos. In CDM cosmolog…
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…
Ray tracing the integrated Sachs-Wolfe effect through the light cones of the Dark Energy Universe Simulation -- Full Universe Runs
Julian Adamek, Yann Rasera, Pier Stefano Corasaniti +1
The late integrated Sachs-Wolfe (ISW) effect correlates the Cosmic Microwave Background (CMB) temperature anisotropies with foreground cosmic large-scale structures. As the correla…
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…
Average Dark Matter Halo Sparsity Relations as Consistency Check of Mass Estimates in Galaxy Cluster Samples
Pier Stefano Corasaniti, Yann Rasera
The dark matter halo sparsity provides a direct observational proxy of the halo mass profile, characterizing halos in terms of the ratio of masses within radii which enclose two di…
Euclid preparation III. Galaxy cluster detection in the wide photometric survey, performance and algorithm selection
Euclid Collaboration, R. Adam, M. Vannier +56
Galaxy cluster counts in bins of mass and redshift have been shown to be a competitive probe to test cosmological models. This method requires an efficient blind detection of clust…
Removal of Galactic foregrounds for the Simons Observatory primordial gravitational wave search
Ben Thorne, Jo Dunkley, David Alonso +6
Upcoming observations from the Simons Observatory have been projected to constrain the tensor-to-scalar ratio, , at the level of 0.003. Here we describe one of the foreca…
Joining bits and pieces of reionization history
Dhiraj Kumar Hazra, Daniela Paoletti, Fabio Finelli +1
Cosmic Microwave Background temperature and polarization anisotropies from Planck have estimated a lower value of the optical depth to reionization () compared to WMAP. A signif…
Cosmic string loop production functions
Pierre Auclair, Christophe Ringeval, Mairi Sakellariadou +1
Numerical simulations of Nambu-Goto cosmic strings in an expanding universe show that the loop distribution relaxes to an universal configuration, the so-called scaling regime, whi…
The galaxy cluster mass scale and its impact on cosmological constraints from the cluster population
G. W. Pratt, M. Arnaud, A. Biviano +5
The total mass of a galaxy cluster is one of its most fundamental properties. Together with the redshift, the mass links observation and theory, allowing us to use the cluster popu…
Constraining the Spin-Dependent WIMP-Nucleon Cross Sections with XENON1T
E. Aprile, J. Aalbers, F. Agostini +126
We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The…
Euclid Preparation IV. Impact of undetected galaxies on weak-lensing shear measurements
Euclid Collaboration, N. Martinet, T. Schrabback +22
In modern weak-lensing surveys, the common approach to correct for residual systematic biases in the shear is to calibrate shape measurement algorithms using simulations. These sim…
Twin LIGO/Virgo Detections of a Viable Gravitationally-Lensed Black Hole Merger
Tom Broadhurst, Jose M. Diego, George F. Smoot
We identify a binary black hole (BBH) merger that appears to be multiply lensed by an intervening galaxy. The LIGO/Virgo events GW170809 and GW170814 have indistinguishable wavefor…
