Immediate deployment opportunities for negative emissions with BECCS: a Swedish case study

Henrik Karlsson, Timur Delahaye, Filip Johnsson +2

To meet the 2°C target and, in particular the 1.5°C target defined in the Paris Agreement, rapid scaling-up of BECCS (Bio-Energy with Carbon Capture and Storage) and other negative…

What can we learn from a sharply falling positron fraction?

Timur Delahaye, Kumiko Kotera, Joseph Silk

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…

Antideuterons from Decaying Gravitino Dark Matter

Timur Delahaye, Michael Grefe

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…

TeV cosmic-ray proton and helium spectra in the myriad model II

Wei Liu, Pierre Salati, Xuelei Chen

Recent observations show that the cosmic ray nuclei spectra start to harden above 100 GeV, in contradiction with the conventional steady-state cosmic ray model. We had suggested th…

Antiproton Limits on Decaying Gravitino Dark Matter

Michael Grefe, Timur Delahaye

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 P…
