Astroparticle physics is a young, interdisciplinary field at the intersections of particle physics, astrophysics, astronomy and cosmology. We want to advance this dynamic field in a very significant way by establishing the Helmholtz Alliance for Astroparticle Physics (HAP).
Alliance partners are
|the Helmholtz Centers KIT and DESY,|
|the 15 German Universities: Aachen, Berlin (HU), Bonn, Dortmund (TU), Dresden (TU), Erlangen-Nürnberg, Hamburg, Mainz, Münster, München (TU), Potsdam, Siegen, Tübingen, Würzburg and Wuppertal|
|and the associated partners:|
|the three Max Planck Institutes: MPIK Heidelberg, MPP München, MPE Garching,|
| the Instituto de Tecnologías en Detección y Astropartículas – ITeDA
(Buenos Aires, Argentina),
| the Laboratoire APC – AstroParticule et Cosmologie (CNRS/IN2P3)
| the GRavitation and AstroParticle Physics in Amsterdam – GRAPPA
| the National Institute for Subatomic Physics – Nikhef
| the Institute for Nuclear Research RAS – INR
| the Skobeltsyn Institute of Nuclear Physics – SINP
Moscow State University (Moscow, Russia),
| and the Kavli Institute for Cosmological Physics – KICP
University of Chicago (Chicago, USA).
There is a total of about 150 senior scientists and 200 doctoral students contributing to HAP.
The Alliance aims for ambitious scientific progress for astroparticle physics at large; however, for its strategic actions it focuses on 4 topics that we address in 8 work packages.
- Astroparticle Theory is a ‘horizontal’ topic that generates interactions throughout all activities within the Alliance. We will develop a detailed and coherent description of Propagation and Detection of high-energy cosmic particles, which is the key to interprete observations in terms of astrophysical source models and parameters. Related to this topic is a better theoretical understanding of Particle Acceleration Sources themselves, also through computer simulations. The third point is about Dark Matter and Non-Acceleration Signatures and how to disentangle their fluxes of accelerated particles.
- The Non-Thermal Universe is an extensive topic that deals with virtually all cosmic particles like protons or heavier nuclei, gamma rays and neutrinos. Their coherent exploit of information is the aim of the Multi-messenger Astroparticle Physics work package, which is closely related to Cosmic Ray Composition and Interactions. In Novel Detection Technologies and Future Challenges we prepare the necessary tools for the large facilities that are required for the future progress of the field.
- The Dark Universe is composed of Dark Matter and Dark Energy, the latter being a working name for the cause of the accelerated expansion of the Universe. Dark Matter is more concrete and manifests itself in gravitational interaction. In two work packages we develop a coherent Analysis of Dark Matter searches and focus on the Key technologies for next-generation Dark Matter experiments.
- Advanced Technologies are described wherever they occur in the other topics. However, we want to give them the visibility of a topic on its own in order to foster the exchange of knowledge and expertise across the Alliance.
