To meet the 2{\deg}C target and, in particular the 1.5{\deg}C target defined in the Paris Agreement, rapid scaling-up of BECCS (Bio-Energy with Carbon Capture and Storage) and other negative emissions technologies (NETs) is essential. Recent research

Cette thèse est dédiée à l'étude de la propagation des électrons et positrons cosmiques dans la Voie Lactée ainsi qu'à la détection indirecte de matière sombre. L'existence de la matière sombre dans l'Univers est une hypothèse raisonnable
Recent results from the AMS-02 data have confirmed that the cosmic ray positron fraction increases with energy between 10 and 200GeV. This quantity should not exceed 50%, and it is hence expected that it will either converge towards 50% or fall. We s

We study the possibility of improving the constraints on the lifetime of gravitino dark matter in scenarios with bilinear R-parity violation by estimating the amount of cosmic-ray antideuterons that can be produced in gravitino decays. Taking into ac

We report on constraints on the lifetime of decaying gravitino dark matter in models with bilinear R-parity violation derived from observations of cosmic-ray antiprotons with the PAMELA experiment. Performing a scan over a viable set of cosmic-ray pr

We derive 95% CL lower limits on the lifetime of decaying dark matter in the channels $Z\nu$, $W\ell$ and $h\nu$ using measurements of the cosmic-ray antiproton flux by the PAMELA experiment. Performing a scan over the allowed range of cosmic-ray pro

Recent measurements of cosmic ray proton and helium spectra show a hardening above a few hundreds of GeV. This excess is hard to understand in the framework of the conventional models of Galactic cosmic ray production and propagation. We propose here
