18 Jun 1997 | | Subject: | astro-ph | | Affiliation: | International School for Advanced Studies, SISSA/ISAS, Italy Osservatorio Astronomico di Brera/Merate, Italy | | Abstract: | The average Spectral Energy Distributions (SED) of different classes of blazars from the radio to the gamma-ray band are studied adopting a "complete-sample" approach. The SED are globally similar, despite systematic differences in specific frequency ranges, showing two broad peaks. However, i) the first and second peak occur in different frequency ranges for different objects, with a tendency for the most luminous sources to peak at lower frequencies, ii) the ratio between the two peak frequencies *seems to be constant*, iii) the luminosity ratio between the high and low frequency component increases with the bolometric luminosity. | | Source: | arXiv, astro-ph/9706190 | | Services: | Forum | Review | PDF | Favorites | |
