On the origin of the ultra-high energy cosmic-rays

Noemie Globus (Visiting Postdoctoral Scholar)
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 also discuss the origin of the UHECR dipole anisotropy recently reported by the Pierre Auger Observatory.

Speaker
Eugene Chiang (UC Berkeley)
The message of the Kepler space mission is this: super-Earths abound in the universe. These are planets 1--4 Earth radii and 2--20 Earth masses in size, and composed of solids and gas in proportions of 100:1 by mass.
