Description

Born in 1997 to provide an optical follow-up of gamma-loud blazars observed by the Compton Gamma Ray Observatory, the Whole Earth Blazar Telescope (WEBT) is a large collaboration including several tens of astronomers around the northern hemisphere who monitor blazars mainly in the optical (including polarimetry), but also in the radio and near-infrared bands. Since 2000 the Collaboration has been led by Italian researchers from the INAF- Osservatorio Astrofisico di Torino and has actively collaborated with other teams, in particular the AGILE, Fermi, and MAGIC ones. The strength of the WEBT is the high temporal resolution of the light curves, which can be obtained thanks to the distribution in longitude of its members. This allows us to study the details of the blazar multiwavelength behaviour, and to propose models for its interpretation. We are looking forward to a fruitful collaboration with the VHE community in the era of the new-generation Cherenkov telescopes.
