Euclid preparation: Testing multi-field inflation with galaxy power spectrum and bispectrum
Euclid Collaboration, D. Linde, A. Moradinezhad Dizgah +281
Primordial non-Gaussianity (PNG) is a powerful probe of the origin of cosmic structure. Stage-IV surveys like \Euclid will measure galaxy - and -point clustering at high sign…
Correlation between H emitters and their cosmic web environment at
Ivan Rapoport, Vincent Desjacques, Ehud Behar +1
Future near-infrared spectroscopic galaxy surveys will target high-redshift emission-line galaxies (ELGs) to test cosmological models. Deriving optimal constraints from emission-li…
Modeling spatially-resolved galactic H emission for galaxy clustering
Ivan Rapoport, Vincent Desjacques, Gabriele Parimbelli +2
Near-infrared spectroscopic surveys target high-redshift emission-line galaxies (ELGs) to probe cosmological scenarios. Understanding the clustering properties of ELGs is essential…
Large-Scale-Structure Observables in General Relativity Validated at Second Order
Antoine Villey, Yonadav Barry Ginat, Vincent Desjacques +2
We present a second-order calculation of relativistic large-scale-structure observables in cosmological perturbation theory, specifically the "cosmic rulers and clock", which are t…
Detection prospects for the GW background of Galactic (sub)solar mass primordial black holes
Frans van Die, Ivan Rapoport, Yonadav Barry Ginat +1
In multi-component dark matter models, a fraction of the dark matter could be in the form of primordial black holes (PBHs) with (sub)solar masses. Some would have fo…
The Irrelevance of Primordial Black Hole Clustering in the LVK mass range
F. Crescimbeni, V. Desjacques, G. Franciolini +6
We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…
