SHORT DESCRIPTION<\/strong><\/h5>\n\n\n\n

WEBT<\/strong> is an international research project aimed at performing and interpreting both photometric and polarimetric observations in the optical, near-infrared (NIR) and radio bands of blazars<\/strong>, which are peculiar <\/em>active galactic nuclei (AGN) characterized by relativistic jets of plasma oriented in directions close to the line of sight from Earth.<\/p>\n\n\n\n

The WEBT<\/strong> collaboration conducts internationally coordinated campaigns involving dozens of telescopes, including small aperture ones, spread across all continents in order to guarantee continuous temporal coverage and a high density of measurements over time.<\/p>\n\n\n\n

Both professional and amateur groups participate in the collaboration, and there are intense collaborations with groups that conduct observations in the high-energy bands, from ultraviolet to X-rays and gamma rays.<\/p>\n\n\n\n

The collaboration is led by Claudia Raiteri<\/strong> and Massimo Villata<\/strong>, from INAF – Turin Astrophysical Observatory<\/a>.<\/p>\n\n\n\n

ROLE OF THE OBSERVATORY<\/h5>\n\n\n\n

The contribution of the Brera Astronomical Observatory is guaranteed by our researcher Giacomo Bonnoli<\/strong>, who coordinates the activities of some telescopes in Italy (Astronomical Observatory of the University of Siena<\/a>, Provincial Observatory of Montarrenti – Siena<\/a>, and their collaborators) and in Spain (Sierra Nevada Observatory<\/a>, Calar Alto Observatory<\/a>) and coordinates joint observation campaigns with the MAGIC Telescopes<\/a>.<\/p>\n\n\n\n
