DESCRIPTION:Speakers: Tanya Edwards (Max-Planck-Institut für Kernphysik)\
 nGround-based gamma-ray astronomy is still tackling a major problem: backg
 round. Reconstruction techniques exist to distinguish most of the backgrou
 nd of hadrons but an irreducible background of electrons and gamma-like pr
 otons still remain. I present here a new technique making use of direct Ch
 erenkov light and air shower development that provides a way to efficientl
 y distinguish between electrons and gamma-rays for the first time. In addi
 tion to this\, the remaining proton background can also be identified. Thi
 s analysis increases the sensitivity of Imaging Atmospheric Cherenkov Tele
 scopes and allows an improved measurement of the cosmic electron spectrum.
  I also discuss further applications of this approach to the studies on di
 ffuse emissions\, extended sources and cosmic ray composition.\n\nhttps://
