摘要:

自2005年9月以来,惠普尔10米伽马射线望远镜主要作为耀变体监测器运行。惠普尔天文台已经探测到的五颗北半球耀变体,即Markarian 421、H1426+428、Markarian 501、1 ES 1959+650和1 ES 2344+514,每晚都会进行常规监测,以确保它们是可见的。我们报告的Markarian 421观测从2005年11月至2006年6月在伽马射线,X射线,光学和无线电波段。在此期间,发现Markarian 421在探测的所有波长下都是可变的。详细研究了不同能区之间的变化和相关性。一个试探性的相关性,与大的扩展,测量之间的X射线和伽马射线带,而没有明确的相关性是明显的其他能带。除此之外,Markarian 421(1101+384)的良好采样的光谱能量分布是为三个不同的活动水平。其他blazar目标的观测结果将单独报告。

英文摘要:

Since September 2005, the Whipple 10m Gamma-ray Telescope has been operated primarily as a blazar monitor. The five Northern Hemisphere blazars that have already been detected at the Whipple Observatory, Markarian 421, H1426+428, Markarian 501, 1ES 1959+650 and 1ES 2344+514, are monitored routinely each night that they are visible. We report on the Markarian 421 observations taken from November 2005 to June 2006 in the gamma-ray, X-ray, optical and radio bands. During this time, Markarian 421 was found to be variable at all wavelengths probed. Both the variability and the correlations among different energy regimes are studied in detail here. A tentative correlation, with large spread, was measured between the X-ray and gamma-ray bands, while no clear correlation was evident among the other energy bands. In addition to this, the well-sampled spectral energy distribution of Markarian 421 (1101+384) is presented for three different activity levels. The observations of the other blazar targets will be reported separately.
