The interaction of a large-scale nuclear wind with the high velocity HII region G0.17+0.15
F. Yusef-Zadeh, Jun-Hui Zhao, R. Arendt +4
We investigate the nature of a Galactic center source, G0.17+0.15, lying along the northern extension of the Radio Arc near l~0.2deg. G0.17+0.15 is an HII region located toward the…
Revealing the Physical Conditions around Sgr A* using Bayesian Inference -- I. Observations and Radiative Transfer
Tomas A. James, Serena Viti, Farhad Yusef-Zadeh +2
We report sub-arcsecond ALMA observations between 272 - 375 GHz towards Sgr A*'s Circumnuclear disk (CND). Our data comprises 8 individual pointings, with significant SiO (8(7) - 7…
Cosmic-ray Particles in the Galactic Center: Blowing in the Wind
F. Yusef-Zadeh, M. Wardle, I. Heywood +2
Recent results from multi-wavelength observations of the inner few hundred pc of the Galactic center have added two new characteristics to the ISM in this unique region. One is the…
ALMA Detection of Bipolar Outflows: Evidence for Low Mass Star Formation within 1pc of Sgr A*
F. Yusef-Zadeh, M. Wardle, D. Kunneriath +3
We report the discovery of 11 bipolar outflows within a projected distance of 1pc from Sgr A* based on deep ALMA observations of CO, H30 and SiO (5-4) lines with sub-arcs…
Tidal Distortion of the Envelope of an AGB Star IRS 3 near Sgr A*
F. Yusef-Zadeh, M. Wardle, W. Cotton +4
We present radio and mm continuum observations of the Galactic center taken with the VLA and ALMA at 44 and 226 GHz, respectively. We detect radio and mm emission from IRS 3, lying…
ALMA and VLA Observations: Evidence for Ongoing Low-mass Star Formation near Sgr A*
F. Yusef-Zadeh, W. Cotton, M. Wardle +5
Using the VLA, we recently detected a large number of protoplanetary disk (proplyd) candidates lying within a couple of light years of the massive black hole Sgr A*. The bow-shock…
