Transport parameters from AMS-02 F/Si data and fluorine source abundance

E. Ferronato Bueno, L. Derome, Y. Génolini +3

The AMS-02 collaboration recently released cosmic-ray F/Si data of unprecedented accuracy. Cosmic-ray (CR) fluorine is predominantly produced by fragmentation of heavier progenitor…

The rigidity dependence of galactic cosmic-ray fluxes and its connection with the diffusion coefficient

M. Vecchi, P. -I. Batista, E. F. Bueno +3

Thanks to tremendous experimental efforts, galactic cosmic-ray fluxes are being measured up to the unprecedented per cent precision level. The logarithmic slope of these fluxes is…

The importance of Fe fragmentation for LiBeB analyses: Is a Li primary source needed to explain AMS-02 data?

D. Maurin, E. Ferronato Bueno, Y. Génolini +2

High-precision data from AMS-02 on Li, Be, and B provide the best constraints on Galactic cosmic-ray transport parameters. We re-evaluate the impact of Fe fragmentation on the Li,…

New minimal, median, and maximal propagation models for dark matter searches with Galactic cosmic rays

Yoann Génolini, Mathieu Boudaud, Marco Cirelli +5

Galactic charged cosmic rays (notably electrons, positrons, antiprotons and light antinuclei) are powerful probes of dark matter annihilation or decay, in particular for candidates…

Revisiting primordial black holes capture into neutron stars

Yoann Génolini, Pasquale Serpico, Peter Tinyakov

Primordial black holes (PBH), produced through a variety of processes in the early universe, could fill galactic halos accounting for a fraction or the totality of the dark matter.…

Combined analysis of AMS-02 (Li,Be,B)/C, N/O, 3He, and 4He data

Nathanael Weinrich, Yoann Génolini, Mathieu Boudaud +2

The AMS-02 experiment measured several secondary-to-primary ratios enabling a detailed study of Galactic cosmic-ray transport. We constrain previously derived benchmark scenarios (…

AMS-02 antiprotons' consistency with a secondary astrophysical origin

Mathieu Boudaud, Yoann Génolini, Laurent Derome +4

The AMS-02 experiment has ushered cosmic-ray physics into precision era. In a companion paper, we designed an improved method to calibrate propagation models on B/C data. Here we p…

Fitting B/C cosmic-ray data in the AMS-02 era: A cookbook

L. Derome, D. Maurin, P. Salati +3

AMS-02 on the International Space Station has been releasing data of unprecedented accuracy. This poses new challenges for their interpretation. We refine the methodology to get a…

A new look at the cosmic ray positron fraction

Mathieu Boudaud

The positron fraction in cosmic rays was found to be steadily increasing in function of energy, above 10 GeV. This behaviour contradicts standard astrophysical mechanisms, in…

M. Boudaud, S. Aupetit, S. Caroff +10

The positron fraction in cosmic rays was found to be a steadily increasing in function of energy, above 10 GeV. This behaviour contradicts standard astrophysical mechanisms,…
