cds-question@unistra.frquasarsspectral-energy-distributionx-ray-sourcesinfrared-photometryvisible-astronomybroad-band-photometryradio-sourcesWe have conducted a detailed investigation of the broadband spectral properties of the {gamma}-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS, Cat. J/ApJ/700/597). By combining our accurately estimated Fermi {gamma}-ray spectra with Swift, radio, infra-red, optical, and other hard X-ray/{gamma}-ray data, collected within 3 months of the LBAS data taking period, we were able to assemble high-quality and quasi-simultaneous spectral energy distributions (SED) for 48 LBAS blazars. We have used these SED to characterize the peak intensity of both the low- and the high-energy components. The results have been used to derive empirical relationships that estimate the position of the two peaks from the broadband colors (i.e., the radio to optical, {alpha}_ro_, and optical to X-ray, {alpha}_ox_, spectral slopes) and from the {gamma}-ray spectral index. While more than 50% of known radio bright high energy peaked (HBL) BL Lacs are detected in the LBAS sample, only less than 13% of known bright broad-lined flat spectrum radio quasars (FSRQs) and LBL BL Lacs are included. This suggests that the latter sources, as a class, may be much fainter {gamma}-ray emitters than LBAS blazars, and could in fact radiate close to the expectations of simple synchrotron self-Compton (SSC) models. We categorized all our sources according to a new physical classification scheme based on the generally accepted paradigm for Active Galactic Nuclei and on the results of this SED study.2010ApJ...716...30Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/716/30CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)J/ApJS/194/29 : Observations of blazars at 15GHz (Richards+, 2011)J/A+A/520/A47 : Blazars in the Swift-BAT hard X-ray sky (Maselli+, 2010)J/ApJ/709/1407 : SED of the Fermi blazars (Li+, 2010)J/ApJ/699/603 : Evolution of Swift/BAT blazars (Ajello+, 2009)J/ApJ/700/597 : FERMI LAT detected blazars (Abdo+, 2009)J/A+A/495/691 : Multifrequency catalogue of blazars, Roma-BZCAT (Massaro+,J/ApJS/171/61 : All-Sky Survey of Flat-Spectrum Radio Sources (Healey+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/716/30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/716/30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/716/30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/716/30https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/716/30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/716/30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/716/30/blazars (Blazar source list and SED parameter)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/716/30/blazars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/716/30/blazars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/716/30/blazars?GETtext/xml+votable180.050000true4.399167-5.2115560.0055555555555555566/579 911 2122 2295 2331 2414 2836 3431 4695 4770 5162 5423 5817 5918 6018 6088 6368 6507 6777 6963 7045 7346 7426 7446 7896 8299 8466 8915 9075 9460 9612 9632 10422 11081 11153 11212 11649 12604 12619 13485 13664 13927 14854 15969 16027 16298 16720 16796 17186 17364 17579 17857 17927 18315 18624 19370 19398 19622 19831 20099 21121 21564 23121 23897 24084 24608 24845 25302 25677 25818 26131 26292 27060 27243 27311 27433 28342 28479 28492 28517 29016 30193 31663 31894 32311 33774 33825 33964 34123 34209 34428 34461 34572 35079 35281 35706 35786 36058 36151 36554 36941 37529 42980 42981 44069 44247 44908 45011 46055 46251 46740 47014 47375 48123 490713.313034785154005e-24 1.2058628298368645e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/716/30?format=asciiX-rayOpticalInfraredRadiodefaultJ/ApJ/716/30/blazarsBlazar source list and SED parameterrecnoRecord number assigned by the VizieR team.
