摘要：

Blazars are a small fraction of all extragalactic sources but, unlike other objects, they are strong emitters across the entire electromagnetic spectrum. Available data at microwave frequencies allow for systematic studies of blazars over large cosmological volumes. At these frequencies the contamination from radio extended components with steep spectra is no longer present and the emission from the accretion process is negligible. Moreover, in the first 3 months of scientific operations Fermi-LAT detected 106 bright, high-galactic latitude (vertical bar b vertical bar> 10 deg) AGNs with high significance. In this study we investigate the possible relations between the microwave and the gamma-ray emissions for Fermi-LAT detected AGNs belonging to WMAP 5th year bright source catalog.
