Describing massive neutrinos in cosmology as a collection of independent flows
Hélène Dupuy, Francis Bernardeau
A new analytical approach allowing to account for massive neutrinos in the non-linear description of the growth of the large-scale structure of the universe is proposed. Unlike the…
Can all cosmological observations be accurately interpreted with a unique geometry?
Pierre Fleury, Hélène Dupuy, Jean-Philippe Uzan
The recent analysis of the Planck results reveals a tension between the best fits for (Ωm0, H0) derived from the cosmic microwave background or baryonic acoustic oscillations on th…
Interpretation of the Hubble diagram in a nonhomogeneous universe
Pierre Fleury, Hélène Dupuy, Jean-Philippe Uzan
In the standard cosmological framework, the Hubble diagram is interpreted by assuming that the light emitted by standard candles propagates in a spatially homogeneous and isotropic…
Atmospheric escape from HD 189733b observed in HI Lyman-alpha: detailed analysis of HST/STIS September 2011 observations
Vincent Bourrier, Alain Lecavelier des Etangs, Hélène Dupuy +8
Observations of transits of the hot giant exoplanet HD 189733b in the unresolved HI Lyman-alpha line show signs of hydrogen escaping the upper atmosphere of the planet. New resolve…
