论文摘要
使用Fermi-Lat，Swift-XRT，Swift-Uvot和Smarts望远镜收集的多波段数据对Blazar PKS 1424-418进行了研究（2012年3月14日至2013年11月4日）。通过分析伽马光光曲线来鉴定两个耀斑的发作。在这两个耀斑期间获得了同时获得多波带光谱分布（SED）。对IR光学和$γ$ ray数据的互相关分析表明，来自同一地区的这些排放的起源。我们使用在耀斑期间从该来源观察到的最高能量光子为多普勒因子设定了下限，应为$> $ 12。通过使用松性发射机制对SED进行建模研究宽带发射机制。
A study of blazar PKS 1424-418 was carried out using multi waveband data collected by Fermi-LAT, Swift-XRT, Swift-UVOT and SMARTS telescopes between MJD 56000 to MJD 56600 (14 Mar 2012 to 4 Nov 2013). Two flaring episodes were identified by analysing the gamma ray light curve. Simultaneous multi waveband Spectral Energy Distributions (SED) were obtained for those two flaring periods. A cross-correlation analysis of IR-Optical and $γ$-ray data suggested the origin of these emissions from the same region. We have set a lower limit for the Doppler factor using the highest energy photon observed from this source during the flaring periods, which should be $>$12. The broadband emission mechanism was studied by modelling the SED using leptonic emission mechanism.
