Connections between cosmic-ray physics, gamma-ray data analysis and Dark Matter detection

Understand

Cosmic-ray (CR) physics has been a prolific field of research for over a century.

• The open problems related to CR acceleration, transport and modulation are deeply connected with the indirect searches for particle dark matter (DM).
• In particular, the high-quality gamma-ray data released by Fermi-LAT are under the spotlight in the scientific community because of a recent claim about a inner Galaxy anomaly: The necessity to disentangle the astrophysical emission due to CR interactions from a possible DM signal is therefore compelling and requires a deep knowledge of several non-trivial aspects regarding CR physics.
• I review all these connections in this contribution.
