Discovery of hard-spectrum y-ray emission from the BL Lacertae object 1ES 0414+009
(EDP Sciences, 2012)Context. 1ES 0414 + 009 (z = 0.287) is a distant high-frequency-peaked BL Lac object, and has long been considered a likely emitter of very-high-energy (VHE, E > 100 GeV) γ-rays due to its high X-ray and radio flux. Aims. ...
