摘要:

普朗克卫星和费米卫星在轨道上的共存,使得在大样本的耀变体中探索(亚)毫米和伽马射线发射之间的联系成为可能。我们发现,伽马射线的发射和(分)毫米光度相关超过五个数量级。然而,当考虑同时观测时,这种相关性在某些频带上并不显著。另一方面,最显著的统计相关性出现在两个月内的准同时观测。此外,我们发现,在中间的毫米波政权的近似频谱营业额的源更有可能是强伽马射线发射器。这些结果表明,新注入的等离子体成分的射流和高水平的伽马射线发射之间的物理关系。

英文摘要:

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. 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 2 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.
