cds-question@unistra.fractive-galactic-nucleigamma-ray-astronomyBlazars are known for their energetic multiwavelength flares from radio wavelengths to high-energy {gamma}-rays. In this work, we study radio, optical, and {gamma}-ray light curves of 145 bright blazars spanning up to 8 yr, to probe the flaring activity and interband correlations. Of these, 105 show >1{sigma} correlations between one or more wavebands, 26 of which have a >3{sigma} correlation in at least one wavelength pair, as measured by the discrete correlation function. The most common and strongest correlations are found between the optical and {gamma}-ray bands, with fluctuations simultaneous within our ~30d resolution. The radio response is usually substantially delayed with respect to the other wavelengths with median time lags of ~100-160d. A systematic flare identification via Bayesian block analysis provides us with a first uniform sample of flares in the three bands, allowing us to characterize the relative rates of multiband and 'orphan' flares. Multiband flares tend to have higher amplitudes than 'orphan' flares.2018MNRAS.480.5517Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/480/5517CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/480/5517https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/480/5517http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/480/5517https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/480/5517https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/480/5517http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/480/5517GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/480/5517/tablea1 (Cross-correlation results for the sources in our that showed a >1{sigma} significant DCF peak)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/480/5517/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/480/5517/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/480/5517/tablea1?GETtext/xml+votable180.050000true4.3992389-5.21160250.0055555555555555566/100 514 911 1085 2094 2295 2414 3023-3024 3431 4695 4770 4820 4964 5284 5462 5817 5918 6018 6067 6088 6507 6647 6822 6888 7004 7038 7045 7346 7426 7548 7758 8067 8199 8321 8466 8915 8972 9196 9460 9633 9676 9723 10183 10280 10422 10605 10800 10843 11153 11212 11444 11522 11639 11649 12599 12604 12619 13179 13410 13640 13673 13705 13711 13820 13927 14797 15211 15286 15917 15969 16027 16298 16796 17184 17186 17364 17414 17516 17579 18253 18457 18624 18661 19370 19398 19756 19831 19907 20099 20141 21574 21768 21793 21935 21972 22363 22396 22501 22950 23015 23121 23127 23215 23691 23835 24027 24260 25302 25630 25677 25910 26131 26303 26483 26695 26798 26983 27060 27310 28083 28352 28479 28492 28498 28517 29017 29729 30036 30842 31430 31663-31664 31894 32261 32311 32621 32712 36554 40689 40762 40766 48798 49037https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/480/5517?format=asciiGamma-raydefaultJ/MNRAS/480/5517/tablea1Cross-correlation results for the sources in our that showed a >1{sigma} significant DCF peakSimbadNameSimbad column added by the CDSmeta.idcharnullablez?
