cds-question@unistra.frquasarsgalaxiesspectroscopyThe high energy spectrum of 3C 273 is usually understood in terms of inverse-Compton emission in a relativistic leptonic jet. This model predicts variability patterns and delays that could be tested with simultaneous observations from the radio to the GeV range. The instruments IBIS, SPI, JEM-X on board INTEGRAL, PCA on board RXTE, and LAT on board Fermi have enough sensitivity to follow the spectral variability of 3C 273 from the keV to the GeV. We looked for correlations between the different energy bands, including radio data at 37GHz collected at the Metsahovi Radio Observatory and built quasi-simultaneous multiwavelength spectra in the high energy domain when the source is flaring either in the X-rays or in the {gamma} rays.2015A&A...576A.122Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/576/A122CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/MNRAS/392/1181 : BV(RI)c photometry of 3C 273 (Dai+, 2009)J/ApJS/213/26 : Optical light curves of PHL1811 and 3C273 (Fan+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/576/A122https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/576/A122http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/576/A122https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/576/A122https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/576/A122http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/576/A122GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/576/A122/pcaspectSED at PCA flaring time (yellow points in Fig. 7)recnoRecord number assigned by the VizieR team.
