Phase Retrieval Problem. Application to VLBI Mapping of Active Galactic Nuclei
A. T. Bajkova
The well-known phase problem which means image reconstruction from only spectrum magnitude without using any spectrum phase information is considered basically in application to VL…
Multi-frequency synthesis algorithm based on Generalized Maximum Entropy Method. Application to 0954+658
Anisa T. Bajkova, Alexander B. Pushkarev
We propose the multi-frequency synthesis (MFS) algorithm with spectral correction of frequency-dependent source brightness distribution based on maximum entropy method. In order to…
Multifrequency VLBA study of the blazar S5 0716+714 during the active state in 2004 II. Large-scale jet kinematics and the comparison of the different methods of VLBI data imaging as applied to kinematic studies of AGN
Elizaveta A. Rastorgueva, Kaj J. Wiik, Anisa T. Bajkova +4
We study the jet kinematics of the blazar S5 0716+714 during its active state in 2003-2004 with multi-epoch VLBI observations. Aims. We present a kinematic analysis of the large-sc…
Multifrequency Method for Mapping Active Galactic Nuclei with Allowance for the Frequency-Dependent Image Shift
Anisa T. Bajkova, Alexander B. Pushkarev
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-d…
Structure of the Radio Source 3C 120 at 8.4 GHz from VLBA+ Observations in 2002
Anisa T. Bajkova, Aleksandr B. Pushkarev
Maps of the radio source 3C 120 obtained from VLBA+ observations at 8.4 GHz at five epochs in January - September 2002 are presented. The images were reconstructed using the maximu…
Reconstructing Images from Projections Using the Maximum-Entropy Method. Numerical Simulations of Low-Aspect Astrotomography
Anisa T. Bajkova
The reconstruction of images from a small number of projections using the maximum-entropy method (MEM) with the Shannon entropy is considered. MEM provides higher-quality image rec…
