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…
