Multi-wavelength observations of Mrk421 and Mrk501 — •Lea Heckmann and David Paneque for the MAGIC collaboration — Max Planck Institute for Physics, Munich, Germany

Blazars, together with other active galactic nuclei, are the most luminous persistent sources in our universe; and therefore a prime candidate for very-high-energy gamma-ray observations. For the two MAGIC telescopes, the Mrk421 and Mrk501 galaxies are amongst the brightest observed objects due to their proximity. Hence, besides single detections during flaring periods, as it is the case for most blazars, also detailed studies of low emission states can be accomplished. Even though blazars have been observed for decades, their jet structures, particle populations and emission mechanism are still intensely discussed, and extensive monitoring campaigns covering the whole electromagnetic spectrum are organised to collect data that will help us understand these extreme objects. Spectral, variability and correlation studies and their evolution over many years are crucial techniques to put constraints on the existing theoretical models that describe the broadband emission and the blazar environments. This talk aims to give an insight into some of the efforts made for the described purpose using data collected on Mrk421 and Mrk501.
