Abstract (from CDS):

The 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, >100GeV) 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 1-10TeV 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.
