BL Lac型天体的光谱能量分布和高能发射

Spectral energy distributions and high-energy emission of BL Lac type objects

Sergey Troitsky

摘要:

基于从Veron和Quasars.org目录的标识,我们确定了201 BL Lac型对象(BLL)的样本的光学到X射线光谱指数,并搜索在高能量波段检测到的源的这些指数的分布趋势。我们发现,EGRET检测到的源是低能量峰值和超高能宇宙射线从先前研究的AGASA,雅库茨克和高分辨率蝇眼样本的到达方向的位置相关性是由低能量峰值的BLL为主。

英文摘要:

Based on identifications from the Veron and Quasars.org catalogs, we determine the optical-to-X-ray spectral indices for a sample of 201 BL Lac type objects (BLLs) and search for trends in the distribution of these indices of the sources detected in high-energy bands. We find that EGRET-detected sources are low-energy peaked and that the positional correlation with the arrival directions of ultra-high-energy cosmic rays from the previously studied AGASA, Yakutsk and High Resolution Fly's Eye samples is dominated by low-energy-peaked BLLs.
