The inner 300 parsec of the Galactic Centre seen by H.E.S.S.

Speaker: Emmanuel Moulin, CEA-Saclay.

Host: Alejandro de La Puente, Carleton U.

Abstract:
The Galactic Centre region has been observed by the High Energy Stereoscopic System (H.E.S.S.) array of ground-based Cherenkov telescopes since 2004 leading to the detection of the very-high-energy (VHE, E > 100 GeV) gamma-ray source HESS J1745−290 spatially coincident with the supermassive black hole Sgr A*. Diffuse TeV gamma-ray emission has been detected along the Galactic plane, most likely due to cosmic-ray interactions with the dense gas of the Central Molecular Zone. The rich 2004-2013 dataset allows for detailed spectral and morphological studies the inner 200 pc of the Galactic Centre region. The new results allow us to make an important statement regarding the location and origin of the accelerator of the parent ultrarelativistic particles. I will discuss the H.E.S.S. observations of the Galactic Centre region in the context of the origin of Galactic cosmic rays.
