Highlights on the first Fermi LAT multi-frequency campaign dedicated on the source BL Lacer-tae are presented in this poster. The coordinated campaign held from the end of August to the end of October 2008 saw the participation of radio (Metsahovi) telescopes, near-IR and optical telescopes, and the participation of RXTE and Swift telescopes. For the first time the broad band radio-to-gamma-ray behavior of the eponymous blazar is revealed during a quiescent state with unprecedented energy coverage thanks to this campaign. This allows to put new insights on the location of the emitting regions with respect to the Broad Line Region, on the variability behavior during the long quiescence periods between major outbursts, and on the sites were the high-energy radiation (X-ray and gamma-ray photons) is produced.

Abstract
Highlights on the first Fermi LAT multi-frequency campaign dedicated on the source BL Lacer-tae are presented in this poster. The coordinated campaign held from the end of August to the end of October 2008 saw the participation of radio (Metsahovi) telescopes, near-IR and optical telescopes, and the participation of RXTE and Swift telescopes. For the first time the broad band radio-to-gamma-ray behavior of the eponymous blazar is revealed during a quiescent state with unprecedented energy coverage thanks to this campaign. This allows to put new insights on the location of the emitting regions with respect to the Broad Line Region, on the variability behavior during the long quiescence periods between major outbursts, and on the sites were the high-energy radiation (X-ray and gamma-ray photons) is produced.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
