dc.description.abstractThe HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100 GeV) γ-rays along the Galactic plane, covering the region 30° < l < 60°, 280° < l < 330°, and −3° < b < 3°. In this continuation of the HESS Galactic Plane Scan, a new extended VHE γ-ray source was discovered at α2000=19h12m49s, δ2000=+10◦09°06'' (HESS J1912+101). Its integral flux between 1–10 TeV is ∼10% of the Crab Nebula flux in the same energy range. The measured energy spectrum can be described by a power law dN/dE ∼ E−Γ with a photon index Γ = 2.7 ± 0.2stat ± 0.3sys. HESS J1912+101 is plausibly associated with the high spin-down luminosity pulsar PSR J1913+1011. We also discuss associations with an as yet unconfirmed SNR candidate proposed from low frequency radio observation and/or with molecular clouds found in ¹³CO data.
