Structure formation with causal bulk viscosity
Giovanni Acquaviva, Anslyn John, Aurélie Pénin
Dissipative features of dark matter affect its clustering properties and could lead to observable consequences for the evolution of large--scale structure. We analyse the evolution…
Line-Intensity Mapping: 2017 Status Report
Ely D. Kovetz, Marco P. Viero, Adam Lidz +45
Following the first two annual intensity mapping workshops at Stanford in March 2016 and Johns Hopkins in June 2017, we report on the recent advances in theory, instrumentation and…
A scale dependent bias on linear scales: the case for HI intensity mapping at z=1
Aurélie Pénin, Obinna Umeh, Mario Santos
Neutral hydrogen (HI) will soon be the dark matter tracer observed over the largest volumes of Universe thanks to the 21 cm intensity mapping technique. To unveil cosmological info…
Dark matter perturbations and viscosity: a causal approach
Giovanni Acquaviva, Anslyn John, Aurélie Pénin
The inclusion of dissipative effects in cosmic fluids modifies their clustering properties and could have observable effects on the formation of large scale structures. We analyse…
Narrow band selected high redshift galaxy candidates contaminated by lower redshift O[III] ultrastrong emitter line galaxies
Aurélie Pénin, Jean-Gabriel Cuby, Benjamin Clément +4
Context. Lyman Break Galaxies (LBG) and Narrow Band (NB) surveys have been successful at detecting large samples of high-redshift galaxies. Both methods are subject to contaminatio…
Non-Gaussianity of the Cosmic Infrared Background anisotropies II : Predictions of the bispectrum and constraints forecast
Aurélie Pénin, Fabien Lacasa, Nabila Aghanim
Using a full analytical computation of the bispectrum based on the halo model together with the halo occupation number, we derive the bispectrum of the cos- mic infrared background…
Non-Gaussianity of the Cosmic Infrared Background anisotropies I : Diagrammatic formalism and application to the angular bispectrum
Fabien Lacasa, Aurélie Pénin, Nabila Aghanim
We present the first halo model based description of the Cosmic Infrared Background (CIB) non-Gaussianity (NG) that is fully parametric. To this end, we introduce, for the first ti…
A Multifrequency approach of the cosmological parameter estimation in presence of extragalactic point sources
D. Paoletti, N. Aghanim, M. Douspis +4
We present a multifrequency approach which optimizes the constraints on cosmological parameters with respect to extragalactic sources and secondary anisotropies contamination on sm…
Modeling the evolution of infrared galaxies : clustering of galaxies in the Cosmic Infrared Background
Aurélie Pénin, Olivier Doré, Guilaine Lagache +1
Star-forming galaxies are a highly biased tracer of the underlying dark matter density field. Their clustering can be studied through the cosmic infrared background anisotropies. T…
An accurate measurement of the anisotropies and mean level of the Cosmic Infrared Background at 100 and 160 um
Aurélie Pénin, Guilaine Lagache, Alberto Noriega-Crepo +6
The measurement of the anisotropies in the cosmic infrared background (CIB) is a powerful mean of studying the evolution of galaxies and large-scale structures. These anisotropies…
Modeling the evolution of infrared galaxies: A Parametric backwards evolution model
Matthieu Béthermin, Hervé Dole, Guilaine Lagache +2
We aim at modeling the infrared galaxy evolution in an as simple as possible way and reproduce statistical properties among which the number counts between 15 microns and 1.1 mm, t…
