Südwestdeutscher Verlag für Hochschulschriften Discovery of the first LBL/IBL Objects at Very High Energy Gamma-Rays

20 years after the discovery of the Crab Nebula as a source of very high energy (VHE) gamma-rays, the number of sources discovered >100 GeV using Cherenkov telescopes has quickly grown to almost 100. This book focuses on the search for emission from a particular type of blazars previously undetected at VHE gamma-rays: low-peaked (LBL) and intermediate-peaked (IBL) BL Lacertae objects. These sources emit non-thermal radiation, and exhibit a peak in their radio-to-X-ray spectral energy distribution at UV/IR energies. They dominate source counts from space-borne observations at gamma-ray energies ...
