Abstract

Blazars are jet-dominated extragalactic objects characterized by the emission of strongly variable non-thermal radiation across the entire electromagnetic spectrum. The use of multi-frequency simultaneous data is essential in order to understand the physical processes that take place in these objects. It is now possible to assemble high-quality multi-frequency simultaneous broadband spectra of large and statistically well-defined samples of radio-loud AGN, thanks to Planck, Fermi and Swift simultaneously on orbit, complemented with other space and ground-based observatories. For this study, we have selected four samples of sources. The first three samples are flux limited in the high energy part of the electromagnetic spectrum: the soft X-ray (O.1-2 keY) sample includes 43 sources from the Rosat All Sky Survey Bright Source Catalog, the hard X-ray (15-150 keV) sample includes 34 sources from the Swift-BAT 54 months source catalog and the gamma-ray sample includes 50 sources from the Fermi-LAT 3 months Bright AGN Source List. The fourth sample is radio flux limited, including 104 bright northern and equatorial radio-loud AGN (most of which have been monitored at Metsahovi Radio observatory for many years) with average radio flux density at 37 GHz greater than 1 Jy. We present the methods applied and the results of the analysis performed using Fermi-LAT data for all sources in the four different samples of AGN.
