GRAPPA is the center of excellence in Gravitation and Astroparticle Physics of the U. of Amsterdam.
It consists of seven faculty members – S. Ando, D. Berge, G. Bertone (spokesperson), M.P. Decowski, B. Freivogel, J. Vink and C. Weniger – as well as of outstanding scientists from the Institute for High Energy Physics (IHEF), the ‘Anton Pannekoek’ Institute (API) and the Institute for Theoretical Physics Amsterdam (ITFA).
GRAPPA researchers have wide research interests, including dark matter phenomenology, cosmic rays, high-energy astrophysics, cosmology, black holes physics, gravitational waves, and string theory, and it includes experimental physicists active in the Antares/KM3NeT, ATLAS, CTA, LOFAR, and XENON1T collaborations.
The aim of the new center is to bring together theoretical physicists, astronomers and particle physicists, in order to answer some of the most profound questions in Particle Astrophysics and Cosmology:
- What is the nature of dark matter and dark energy?
- How can the forces of Nature be unified?
- Does this union leave measurable signatures in the present Universe?
- What do black holes and neutron stars teach us about the fundamental laws of physics?
- In what ways are high-energy neutrinos, cosmic rays, gamma rays and gravity waves produced and how do these new messengers enhance our knowledge of the extremes of the Universe?
