Automated analysis of Fermi-LAT data to trigger ground-based gamma-ray   observations
  The Fermi Gamma-ray Space Telescope regularly surveys the entire sky in the energy range between 0.3 and 100 GeV with an homogeneous coverage. This makes Fermi a very useful guide for ground-based Cherenkov-telescope arrays like VERITAS, that are sensitive at energies above 100 GeV. The VERITAS collaboration uses information from Fermi-LAT to select potential targets and identify flaring objects in the GeV band. We describe three different analysis pipelines that automatically process and analyze Fermi-LAT data on a daily basis to look for flaring objects: daily light curves of selected targets, an all-sky analysis to identify new flaring sources, and an algorithm that looks for clusters of high-energy photons in time and arrival direction.
