Fulvio Melia, Siming Liu, Marco Fatuzzo
PAPER WITHDRAWN. The recent detection of Sgr A* in the X-ray band, together with the radio polarization measurements conducted over the past few years, offer the best constraints y…
The Interaction of two Prominent Galactic Center Sources: Sgr A East and the Molecular Ring
F. Yusef-Zadeh, S. Stolovy, M. Burton +4
We present a synthesis of a number of recent observations in the near-IR H_2 and [Fe II] lines, OH (1720 MHz) maser line and various radio continuum measurements using the NICMOS o…
Anisotropy in the Angular Broadening of Sgr A at the Galactic Center
F. Yusef-Zadeh W. Cotton M. Wardle F. Melia, D. Roberts
We present the results of a 20 cm VLA observation of the compact Galactic center radio source Sgr A. The scatter-broadened image is elongated in the East-West direction, wit…
