The gravitational wave detector Virgo is presently being commissioned. A significant part of last year was spent in setting up the cavity length control system. This work was carried out with steps of increasing complexity: locking a simple FabryPerot cavity, then a Michelson interferometer with Fabry-Perot cavities in both arms, and finally recycling the(More)
We report the discovery of faint very high energy (VHE, E > 100 GeV) γ-ray emission from the radio galaxy Centaurus A in deep observations performed with the H.E.S.S. experiment. A signal with a statistical significance of 5.0 σ is detected from the region including the radio core and the inner kpc jets. The integral flux above an energy threshold of ∼250(More)
