2012ApJ...754...23L Exploring the Relation between (Sub-)Millimeter Radiation and gamma-Ray Emission in Blazars with Planck and Fermi Leon-Tavares, J.; Valtaoja, E.; Giommi, P.; Polenta, G.; Tornikoski, M.; Lahteenmaki, A.; Gasparrini, D.; Cutini, S. Abstract. The coexistence of Planck and Fermi satellites in orbit has enabled the exploration of the connection between the (sub-)millimeter and gamma-ray emission in a large sample of blazars. We find that the gamma-ray emission and the (sub-)mm luminosities are correlated over five orders of magnitude, L_gamma_vpropL_(sub-)mm_. However, this correlation is not significant at some frequency bands when simultaneous observations are considered. The most significant statistical correlations, on the other hand, arise when observations are quasi-simultaneous within two months. Moreover, we find that sources with an approximate spectral turnover in the middle of the mm-wave regime are more likely to be strong gamma-ray emitters. These results suggest a physical relation between the newly injected plasma components in the jet and the high levels of gamma-ray emission. Key words: BL Lacertae objects: general, galaxies: jets, galaxies: nuclei, gamma rays: galaxies, quasars: general, submillimeter: galaxies
