Compact Radio Sources within 30" of Sgr A*: Proper Motions, Stellar Winds and the Accretion Rate onto Sgr A*

F. Yusef-Zadeh, H. Bushouse, R. Schödel +5

Recent broad-band 34 and 44 GHz radio continuum observations of the Galactic center have revealed 41 massive stars identified with near-IR counterparts, as well as 44 proplyd candi…

Signatures of Young Star Formation Activity Within Two Parsecs of Sgr A*

F. Yusef-Zadeh, M. Wardle, M. Sewilo +9

We present radio and infrared observations indicating on-going star formation activity inside the pc circumnuclear ring at the Galactic center. Collectively these measure…

Occultation of the Quiescent Emission from Sgr A* by IR Flares

F. Yusef-Zadeh, M. Wardle, H. Bushouse +2

We have investigated the nature of flare emission from Sgr A* during multi-wavelength observations of this source that took place in 2004, 2005 and 2006. We present evidence for di…

The Underluminous Nature of Sgr A*

F. Yusef-Zadeh, M. Wardle

In the last several years, a number of observing campaigns of the massive black hole Sgr A* has been carried out in order to address two important issues: one concerns the underlum…
