Examining the relationship between the bulge-to-total stellar mass ratio and dwarf galaxy count in the context of ΛCDM
Previous results suggest that there is a correlation between the size of the bulge of a galaxy and the number of its dwarf galaxy satellites. This was found to be inconsistent with the standard model of cosmology based on comparisons to semi-analytical dar ...
Les Ulis Cedex A2023The DESI N-body Simulation Project - II. Suppressing sample variance with fast simulations
Andrei Variu, Cheng Zhao, Yu Yu, Hanyu Zhang
Dark Energy Spectroscopic Instrument (DESI) will construct a large and precise three-dimensional map of our Universe. The survey effective volume reaches similar to 20 h(-3) Gpc(3). It is a great challenge to prepare high-resolution simulations with a much ...
OXFORD UNIV PRESS2022MASS-CONCENTRATION RELATION OF CLUSTERS OF GALAXIES FROM CFHTLenS
Jean-Paul Richard Kneib, Huanyuan Shan
Based on weak lensing data from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS), in this paper we study the mass-concentration (M-c) relation for similar to 200 redMaPPer clusters in the fields. We extract the M-c relation by measuring the den ...
Iop Publishing Ltd2015Completing Lorentz violating massive gravity at high energies
Sergey Sibiryakov, Diego Blas Temino
Theories with massive gravitons are interesting for a variety of physical applications, ranging from cosmological phenomena to holographic modeling of condensed matter systems. To date, they have been formulated as effective field theories with a cutoff pr ...
Springer Verlag2015Planck 2013 results. XXVI. Background geometry and topology of the Universe
Julien Lesgourgues, Jason Douglas McEwen, Fabio Finelli
The new cosmic microwave background (CMB) temperature maps from Planck provide the highest-quality full-sky view of the surface of last scattering available to date. This allows us to detect possible departures from the standard model of a globally homogen ...
Edp Sciences S A2014Cosmology From Gravitational Lens Time Delays And Planck Data
Frédéric Courbin, Georges Meylan, Malte Tewes
Under the assumption of a flat Lambda CDM cosmology, recent data from the Planck satellite point toward a Hubble constant that is in tension with that measured by gravitational lens time delays and by the local distance ladder. Prosaically, this difference ...
Iop Publishing Ltd2014Sparsity and the Bayesian perspective
Jean-Luc Starck, Anaïs Marie Rassat
Sparsity has recently been introduced in cosmology for weak-lensing and cosmic microwave background (CMB) data analysis for different applications such as denoising, component separation, or inpainting (i.e., filling the missing data or the mask). Although ...
Edp Sciences S A2013Review of Particle Physics
This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons. We also summa ...
