Constraints from Ly- forests on non-thermal dark matter including resonantly-produced sterile neutrinos
Julien Baur, Nathalie Palanque-Delabrouille, Christophe Yèche +4
We use BOSS DR9 quasars to constrain 2 cases of dark matter models: cold-plus-warm (C+WDM) where the warm component is a thermal relic, and sterile neutrinos resonantly produced in…
Constraining the mass of light bosonic dark matter using SDSS Lyman- forest
Eric Armengaud, Nathalie Palanque-Delabrouille, Christophe Yèche +2
If a significant fraction of the dark matter in the Universe is made of an ultra-light scalar field, named fuzzy dark matter (FDM) with a mass of the order of $10^{-22}-10^{-…
Constraints on neutrino masses from Lyman-alpha forest power spectrum with BOSS and XQ-100
Ch. Yeche, N. Palanque-Delabrouille, J . Baur +1
We present constraints on masses of active and sterile neutrinos. We use the one-dimensional Ly-forest power spectrum from the Baryon Oscillation Spectroscopic Survey (BOSS) of…
Is a symmetric matter-antimatter universe excluded?
Julien Baur, Alain Blanchard, Peter Von Ballmoos
We consider a non-standard cosmological model in which the universe contains as much matter as antimatter on large scales and presents a local baryon asymmetry. A key ingredient in…
Lyman-alpha Forests cool Warm Dark Matter
Julien Baur, Nathalie Palanque-Delabrouille, Christophe Yèche +2
The free-streaming of keV-scale particles impacts structure growth on scales that are probed by the Lyman-alpha forest of distant quasars. Using an unprecedentedly large sample of…
Neutrino masses and cosmology with Lyman-alpha forest power spectrum
Nathalie Palanque-Delabrouille, Christophe Yeche, Julien Baur +9
We present constraints on neutrino masses, the primordial fluctuation spectrum from inflation, and other parameters of the CDM model, using the one-dimensional Ly-forest powe…
