Linearly and Circularly Polarized Emission in Sagittarius A*
L. Huang, S. Liu, Z. -Q. Shen +3
We perform general relativistic ray-tracing calculations of the transfer of polarized synchrotron radiation through the relativistic accretion flow in Sagittarius (Sgr) A*. Based o…
Multi-Frequency VLBI Observations of NRAO 530
S. -W. Feng, Z. -Q. Shen, H. -B. Cai +3
We report on VLBA observations of a gamma-ray bright blazar NRAO 530 at multiple frequencies (5, 8, 15, 22, 39, 43, and 45 GHz) in 1997 and 1999. These multi-epoch multi-frequency…
Molecular outflows around high-mass young stellar objects
Y. Xu, Z. -Q. Shen, J. Yang +7
We present a study of molecular outflows using high-resolution mapping of the CO (1-0) line emission toward eight relatively nearby 6.7 GHz methanol masers, which are associated wi…
Simultaneous Multi-Wavelength Observations of Sgr A*
T. an, W. M. Goss, J. -H. Zhao +4
We observed Sgr A* using the Very Large Array (VLA) and the Giant Metrewave Radio Telescope (GMRT) at multiple cm and mm wavelengths on 17 June 2003. The measured flux densities of…
The simultaneous VLA observations of Sgr A* from 90 to 0.7 cm
T. An, J. -H. Zhao, X. -Y. Hong +4
We present a spectrum of Sgr A* observed simultaneously on June 17, 2003 at wavelengths from 90 to 0.7 cm with the VLA. In the spectrum, we also include the measurements of Sgr A*…
Multi-Frequency VLBI Observations of GHz-Peaked Spectrum Sources
S. Kameno, M. Inoue, Z. -Q. Shen +2
We report results of pentachromatic VLBI survey for 18 GHz-peaked spectrum sources. Spectral fitting at every pixel across five frequencies allows us to illustrate distribution of…
