Multifrequency Method for Mapping Active Galactic Nuclei with Allowance for the Frequency-Dependent Image Shift
摘要:
我们考虑的问题,多频VLBA图像合成和光谱指数映射的活动星系核的必要性,考虑到依赖于频率的图像移位。我们描述了我们的广义多频合成算法的频谱校正的基础上的最大熵方法。本文给出了J2202+4216、J0336+3218和J1419+5423等射电源多频VLBI数据的处理结果。
英文摘要:
We consider the problem of multifrequency VLBA image synthesis and spectral-index mapping for active galactic nuclei related to the necessity of taking into account the frequency-dependent image shift. We describe our generalized multifrequency synthesis algorithm with a spectral correction based on the maximum entropy method. The results of our processing of multifrequency VLBI data for the radio sources J2202+4216, J0336+3218, and J1419+5423 are presented.
