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*…

Intrinsic Size and Shape of Sgr A*: 3.6 AU by <1 AU
K. Y. Lo, Z. -Q. Shen, J. -H. Zhao +1
By means of near-simultaneous multi-wavelength VLBA measurements, we determine for the first time the intrinsic size of Sgr A* to be 3.6 AU by <1 AU with the major axis oriented es…

Sgr A* and Company - Multiwavelength observations of Sgr A* and VLA search of ``Sgr A*'s'' in LINERs
Heino Falcke, W. M. Goss, L. C. Ho +5
We report first results from a multiwavelength campaign to measure the simultaneous spectrum of Sgr A* from cm to mm wavelengths. The observations confirm that the previously detec…
