Extraordinary Astrolunch: Noemie Globus

Title: On the origin of the ultra-high energy cosmic-rays
Abstract: The origin of the ultra-high energy cosmic-rays (UHECRs) is still unknown. I will show that the observational data on the spectrum and composition can be explained by a generic model having one Galactic component and one extragalactic component. I will review the constrains brought by neutrino and gamma-ray experiments on UHECR origin. I will also discuss the origin of the UHECR dipole anisotropy recently reported by the Pierre Auger Observatory.

The workshop: Radio Astronomy - A Time Domain Perspective.

Mon, 01/04/2019 to Thu, 04/04/2019


Radio astronomy is on the rise again as old observatories are rejuvenated with upgraded capabilities, and as new generation facilities are now becoming online. New exciting discoveries are already being made across various fields in radio astronomy.
