Multiwavelength observations of Mrk 501 in 2008 — •Konstancja Satalecka1, Daniel Kranich2, and David Paneque3 — 1DESY, Platanenallee 6, 15378 Zeuthen, Germany — 2Institute for Particle Physics, Swiss Federal Institute of Technology (ETH) Zurich, CH-8093, Switzerland — 3SLAC National Accelerator Laboratory and KIPAC, CA94025, USA
on behalf of the MAGIC Collaboration and all the other instruments/people participating in the Mrk501 MW campaign in 2008.
The well-studied VHE (E > 100 GeV) blazar Mrk 501 has been the target of many multiwavelength (MWL) campaigns, mainly covering the object during a flaring activity. The data presented here were taken between March 25th and May 16th, 2008 during an extended MWL campaign covering radio (Effelsberg, IRAM, Medicina, Metsähovi, Noto, RATAN-600, VLBA), optical (KVA), UV (Swift/UVOT), X-ray (RXTE/PCA, Swift/XRT and Swift/BAT) and γ-ray (MAGIC, Whipple, VERITAS). Mrk 501 was in a low state during the campaign, with a VHE flux of about 20% of the Crab Nebula flux. We present here the multifrequency light curve, the
broad band Spectral Energy Distribution (SED) for two emission states and discuss the observed variability and spectral modeling of the object with a leptonic, homogeneous one-zone synchrotron self-Compton model.
