摘要:

到目前为止,还没有系统的长期blazar监测计划和详细的变化研究存在亚毫米波长。在这里,我们提出了一个新的亚毫米blazar监测计划,使用APEX 12米望远镜。自2007/2008年以来,用345 GHz的LABOCA测辐射热计相机监测了大约40个伽马射线耀变体的样本。第一光变曲线,初步的变化结果和第一次比较与较长的厘米/毫米波段(F-Gamma计划),展示了极端的变化特性的耀变体在这样短的波长。

英文摘要:

So far, no systematic long-term blazar monitoring programs and detailed variability studies exist at sub-mm wavelengths. Here, we present a new sub-mm blazar monitoring program using the APEX 12-m telescope. A sample of about 40 gamma-ray blazars has been monitored since 2007/2008 with the LABOCA bolometer camera at 345 GHz. First light curves, preliminary variability results and a first comparison with the longer cm/mm bands (F-GAMMA program) are presented, demonstrating the extreme variability characteristics of blazars at such short wavelengths.
