Radio Continuum Emission from the Magnetar SGR J1745-2900: Interaction with Gas Orbiting Sgr A*
F. Yusef-Zadeh, R. Diesing, M. Wardle +5
We present radio continuum light curves of the magnetar SGR J17452900 and Sgr A* obtained with multi-frequency, multi-epoch Very Large Array observations between 2012 and 2014.…
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…
Radio Continuum Observations of the Galactic Center: Photoevaporative Proplyd-like Objects near Sgr A*
F. Yusef-Zadeh, D. A. Roberts, M. Wardle +3
We present radio images within 30 of Sgr A* based on recent VLA observations at 34 GHz with 7.8 microJy sensitivity and resolution milliarcseconds (mas). We re…
