Identification of Potential Weak Target Radio Quasars for ASTRO-G In-Beam Phase-Referencing
S. Frey, K. E. Gabanyi, Y. Asaki
We apply an efficient selection method to identify potential weak Very Long Baseline Interferometry (VLBI) target quasars simply using optical (SDSS) and low-resolution radio (FIRS…
The VSOP 5 GHz Active Galactic Nucleus Survey: V. Imaging Results for the Remaining 140 sources
R. Dodson, E. B. Fomalont, K. Wiik +21
In February 1997, the Japanese radio astronomy satellite HALCA was launched to provide the space-bourne element for the VLBI Space Observatory Programme (VSOP) mission. Approximate…
Verification of the Effectiveness of VSOP-2 Phase Referencing with a Newly Developed Simulation Tool, ARIS
Yoshiharu Asaki, Hiroshi Sudou, Yusuke Kono +8
The next-generation space VLBI mission, VSOP-2, is expected to provide unprecedented spatial resolutions at 8.4, 22, and 43GHz. In this report, phase referencing with VSOP-2 is exa…
On the Near-term Space VLBI Mission VSOP-2
H. Hirabayashi, Y. Murata, P. G. Edwards +6
A second generation near-term space VLBI mission, VSOP-2, is being planned for a launch in 2010 or soon after. The scientific objectives are very high angular resolution imaging of…
The VSOP 5 GHz AGN Survey II. Data Calibration and Imaging
J. E. J. Lovell, G. A. Moellenbrock, S. Horiuchi +18
The VSOP mission is a Japanese-led project to study radio sources with sub-milliarcsecond angular resolution using an orbiting 8-m telescope, HALCA and global arrays of Earth-based…
