An International Survey of Front-End Receivers and Observing Performance of Telescopes for Radio Astronomy
P. Bolli, A. Orfei, A. Zanichelli +18
This paper presents a survey of microwave front-end receivers installed at radio telescopes throughout the World. This unprecedented analysis was conducted as part of a review of f…
5 GHz TMRT observations of 71 pulsars
Ru-Shuang Zhao, Zhen Yan, Xin-Ji Wu +6
We present integrated pulse profiles at 5~GHz for 71 pulsars, including eight millisecond pulsars (MSPs), obtained using the Shanghai Tian Ma Radio Telescope (TMRT). Mean flux dens…
Simultaneous 13 cm/3 cm single-pulse observations of PSR B0329+54
Zhen Yan, Zhi-Qiang Shen, Richard N. Manchester +10
We have investigated the mode-changing properties of PSR B0329+54 using 31 epochs of simultaneous 13 cm/3 cm single-pulse observations obtained with Shanghai Tian Ma 65 m telescope…
VLBI imaging of M81* at 3.4 mm with source-frequency phase-referencing
Wu Jiang, Zhi-qiang Shen, Dong-rong Jiang +2
We report on the first VLBI image of the M81 nucleus (M81*) at a wavelength of 3.4 mm, obtained with the source-frequency phase-referencing (SFPR) technique. Thanks to the SFPR cal…
Investigating multi-frequency pulse profiles of PSRs B0329+54 and B1642-03 in an inverse Compton scattering (ICS) model
L. H. Shang, J. G. Lu, Y. J. Du +17
The emission geometries, e.g. the emission region height, the beam shape, and radius-to-frequency mapping, are important predictions of pulsar radiation model. The multi-band radio…
The Core-like Nature of HST-1 in the M87 Jet
Y. J. Chen, G. -Y. Zhao, Z. -Q. Shen
We investigate the total flux density, spectral, polarization, and Faraday rotation variability of HST-1 in the M87 jet during the outburst from 2003 to 2007 through multi-epoch VL…
A kinematic study of the compact jet in quasar B3 1633+382
Yi Liu, D. R. Jiang, Zhi-Qiang Shen +1
We present a study of the motion of compact jet components in quasar B3 1633+382. Through analyzing 14 epochs of VLBI observations of three components (B1, B2, and B3) at 22 GHz, w…
A Modified Stratified Model for 3C 273 Jet
Wen-Po Liu, Zhi-Qiang Shen
We present a modified stratified jet model to interpret the observed spectral energy distributions of knots in 3C 273 jet. Based on the hypothesis of the single index of the partic…
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…
A Measurement of Proper Motions of SiO Maser Sources in the Galactic Center with the VLBA
T. Oyama, M. Miyoshi, S. Deguchi +2
We report on the high-precision astrometric observations of maser sources around the Galactic Center in the SiO J=1--0 v=1 and 2 lines with the VLBA during 2001 -- 2004. With phase…
