Abstract

Simultaneous multi-wavelength (MW) campaigns are the most promising approaches to investigate the still unrevealed nature of blazars, active galactic nuclei which are variable on all time scales from radio to TeV energies. In 2008, two MW campaigns on the high-frequency peaked blazars Mrk 180 and 1ES 2344+514 have been organised by the MAGIC collaboration. From radio to TeV gamma rays, RATAN-600, Mets\"ahovi, Effelsberg, VLBA (only 1ES 2344+514), IRAM, KVA, Swift, AGILE, Fermi-LAT and MAGIC-I were taking part in these campaigns. Mrk 180 had just been discovered at TeV energies by MAGIC in 2006, whereas 1ES 2344+514 is a known TeV emitter since many years. Due to their rather faint emission particularly at TeV energies, the campaigns represented quite challenging observations. In fact, Mrk 180 has not been investigated until now in MW campaigns, and for 1ES 2344+514 only one campaign including TeV measurements has been reported in literature up to now. In this contribution, we will present detailed MW light curves for both sources and describe the composite wide range spectral energy distributions by theoretical models.
