1307.8070 (Matteo Cerruti et al.)

Upper Limits From Five Years of VERITAS Blazar Observations    [PDF]

Matteo Cerruti, for the VERITAS Collaboration
The VERITAS array of Cherenkov telescopes was used to observe ~130 blazars from 2007 to 2012. Of these, 25 were detected as very-high-energy (VHE; E > 100 GeV) sources. We present here the results of the analysis of 65 VERITAS non-detected blazars, including upper limits on their VHE flux. Results from a stacked analysis of the entire data set and of smaller sub-sets (defined as a function of the redshift and the blazar class) are presented and discussed.
