  1. hele kleine deeltjes & hele grote experimenten Frank Linde (Nikhef) VDL, 15 february 2011

  2. astroparticle physics particle physics astronomy

  3. now Big Bang’s afterglow Big Bang abundance of chemical elements

  4. What is the Universe made of? We barely know 4%! Where is all the antimatter? Universe ought to be symmetric! How did the Universe lookdirectly after the Big Bang? Observe it! Origin of particle masses? Newton didn’t know – neither do we …

  5. Astroparticle physics Accelerator-based particle physics Nikhef research: experiment AUGER cosmic ray observatory Experiments @ CERN: ALICE ATLAS LHCb ANTARES deep-sea neutrino telescope VIRGO gravitational-wave detector XENON-1t deep-underground dark matter detector

  6. Nikhef = collaboration + RuG NIOZ UT LEI TUe ASTRON TUD SRON
