Multiwavelength observations of the AGN 1ES 0414+009 with veritas, FERMI-LAT, SWIFT-XRT, and MDM
We present observations of the BL Lac object 1ES0414+009 in the >200 GeV gamma-ray band by the VERITAS array of Cherenkov telescopes. 1ES0414+009 was observed by VERITAS between 2008 January and 2011 February, resulting in 56.2 hr of good quality pointed observations. These observations resulted...

These observations resulted in a detection of 822 events from the source corresponding to a statistical significance of 6.4 standard deviations (6.4σ) above the background. The source flux, showing no evidence for variability, is measured as (5.2 ± 1.1stat ± 2.6sys) × 10-12 photons cm-2 s-1 above 200 GeV, equivalent to approximately 2% of the Crab Nebula flux above this energy.
