Robustness of cosmic neutrino background detection in the cosmic microwave background
Benjamin Audren, Emilio Bellini, Antonio J. Cuesta +9
The existence of a cosmic neutrino background can be probed indirectly by CMB experiments, not only by measuring the background density of radiation in the universe, but also by se…
Cosmological constraints on deviations from Lorentz invariance in gravity and dark matter
B. Audren, D. Blas, M. M. Ivanov +2
We consider a scenario where local Lorentz invariance is violated by the existence of a preferred time direction at every space-time point. This scenario can arise in the context o…
Strongest model-independent bound on the lifetime of Dark Matter
Benjamin Audren, Julien Lesgourgues, Gianpiero Mangano +2
Dark Matter is essential for structure formation in the late Universe so it must be stable on cosmological time scales. But how stable exactly? Only assuming decays into relativist…
A note of clarification: BICEP2 and Planck are not in tension
Benjamin Audren, Daniel G. Figueroa, Thomas Tram
The apparent discrepancy between the value of the tensor-to-scalar ratio reported by the BICEP2 collaboration, at 68% CL, and the Planck upper limit, $r…
Separate Constraints on Early and Late Cosmology
Benjamin Audren
Since the public release of Planck data, several attempts have been made to explain the observed small tensions with other data-sets, most of them involving an extension of the ΛCD…
Cosmological constraints on Lorentz violating dark energy
B. Audren, D. Blas, J. Lesgourgues +1
The role of Lorentz invariance as a fundamental symmetry of nature has been lately reconsidered in different approaches to quantum gravity. It is thus natural to study whether othe…
