Imprints of Cosmic Rays in Multifrequency Observations of the Interstellar Emission

Understand

Ever since the discovery of Cosmic Rays (CRs), significant advancements have been made in modeling their propagation in the Galaxy and in the Heliosphere.

• However, propagation models suffer from degeneracy of many parameters.
• To complicate the picture the precision of recent data have started challenging existing models.
• To tackle these issues we use available multifrequency observations of the interstellar emission from radio to gamma rays, together with direct CR measurements, to study local interstellar spectra (LIS) and propagation models.
