Astrophysics Seminar

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.

On the origin of the ultra-high energy cosmic-rays
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 and I will discuss the origin of the dipole anisotropy recently reported by the Pierre Auger Observatory.
