| « Fermi-LAT, HESS and beyond, status and future of gamma-ray astronomy » |

Marianne Lemoine-Goumard |
| The field of gamma-ray astronomy has received considerable attention beyond the high-energy astrophysics community in the recent years. This is in part due to the success of Imaging Atmospheric Cherenkov Telescopes (IACTs) such as HESS, MAGIC and VERITAS, measuring gamma-rays in the energy regime above 100 GeV. All these new facilities have lifted gamma-ray astronomy in the last few years from an exotic discipline with a handful of detected sources to a solid astronomical discipline. In addition, the successful launch of Fermi and its main instrument, the Large Area Telescope (LAT), measuring gamma-rays outside Earth's atmosphere in the energy range beyond 20 MeV adds to the attention and excitement. The Fermi-LAT instrument solidifies this discipline by detecting several thousands of new sources and by bridging the energy spectra of ground-based detected VHE gamma-ray sources to well-studies objects at X-ray energies. In this seminar I will discuss the current status of the field, as well as the potential for future observatories. |
