Welcome!

The Particle Physics and High Energy Astrophysics Group of Prof. W. Hofmann (Max-Planck-Institute for Nuclear Physics, Heidelberg, Germany) in collaboration with Prof. F. Aharonian (Dublin Institute for Advanced Studies, Dublin Ireland) and Prof. S. Wagner (Heidelberg Observatory, Heidelberg, Germany) organizes a workshop on "The GeV to TeV Connection", discussing the science in the 10 GeV to 100 GeV energy regime. In the focus of the meeting will be the synergy between satellite (Fermi, Agile) and ground based (H.E.S.S., MAGIC, VERITAS) gamma ray telescopes, with emphasis on the next generation ground based experiments (H.E.S.S. II, MAGIC-II), which will provide a large overlap region in energy with the existing satellite experiments. Physics of galactic (pulsars and pulsar wind nebulas, SNR, binaries, diffuse emission, ..) and extragalactic (AGN, GRB, galaxy clusters, starburst galaxies, ..) sources as well as technical issues will be discussed. The workshop will take place in the conference center of the Max Planck Society, in the Castle Ringberg, near Munich, Bavaria, Germany, from Jan 11 - 16, 2010.

Attendance will be by invitation only.

Astrophysics at high and very high energies is currently experiencing an exciting period of growth and activity: the Fermi satellite, with its unprecedented sensitivity, delivers an astonishing picture of the high energy sky at GeV energies. At very high energies (VHE), the current generation imaging Cherenkov telescopes H.E.S.S., MAGIC, and VERITAS, brought the break-through in VHE astronomy, providing a large number of sources and different source classes. The next generation Cherenkov instruments (H.E.S.S. II, MAGIC-II, currently under construction) will significantly extend the energy range of ground based instruments in the sub 100 GeV domain down to 30 GeV, providing a large overlap in energy with space based instruments. This overlap will, for the first time, enable to combine the power of satellite experiment - large field of view and thereby a constant monitoring of the sky on daily basis - with the sensitivity of ground based instruments at high energies in a common energy range. The combined observations enable to fix the complete high energy part of the spectrum over more than 5 orders of magnitude in energy. It will open up new physics studies for e.g. pulsars or distant active galactic nuclei. The large overlap in energy will also enable to inter-calibrate between the two observational methods. Aim of this workshop is to bring together scientists from space base and ground based high energy observatories to discuss the science in the 10 GeV to 100 GeV energy range for a wide range of galactic (pulsars and pulsar wind nebulas, SNR, binaries, diffuse emission, ..) and extragalactic (AGN, GRB, galaxy clusters, starburst galaxies, ..) topics, as well as technical aspects.

Attendance will be by invitation only. Those wishing to receive further information may contact the workshop secretariat.
