27. A bright (near) future in the PeVatron era with the ASTRI Mini-Array

MARTINA CARDILLO (IAPS-INAF)

Despite the enormous efforts done in very recent years, both theoretically and experimentally, the basic three questions about the Cosmic Ray (CR) origin remain without clear answers: what are their sources, how are they accelerated, how do they propagate?

Gamma-ray astronomy plays a fundamental role in this field. Both relativistic protons and electrons can emit in the gamma-ray band...

28. Cosmic and gamma rays from young supernovae

Dr Alexandre Marcowith (Laboratoire Univers Particle Montpellier)

Supernovae issued from massive star explosion produce collisionless shocks after the breakout. These shocks propagate in the dense circum-stellar wind of the progenitor star. The combination of a high density medium and shock speeds at a fraction of c make these places as potential sites of high energy cosmic ray acceleration because particles can self-drive an efficient magnetic field...

26. Origin of the very high energy gamma-ray emission from the Crab nebula

Gwenael Giacinti (TDLI / SJTU Shanghai)

LHAASO has detected gamma-ray emission from the Crab Nebula up to PeV energies. We show here that our recent model for electron acceleration at pulsar wind termination shocks can fit well both the inverse Compton and the synchrotron emission from the Nebula. Integrating individual particle trajectories in a model of the magnetic field and flow pattern near the shock, we find that drift motion...

31. Search for the Galactic accelerators of Cosmic-Rays up to the Knee with the Pevatron Test Statistic

Ekrem Oguzhan Angüner (CPPM)

The recently introduced PeVatron Test Statistic (PTS) method in the framework of Cherenkov Telescope Array (CTA) PeVatrons study offers a new approach to detect spectral signatures of hadronic PeVatrons. The PTS is, for the first time, applied to PeVatron candidate sources' data from gamma-ray observatories to test for the origin of Cosmic Rays (CRs) at energies around and above the knee of...
