Near-Infrared Variability Study of the Central 2.3 arcmin x 2.3 arcmin of the Galactic Centre II. Identification of RR Lyrae Stars in the Milky Way Nuclear Star Cluster
Hui Dong, Rainer Schodel, Benjamin F. Williams +8
Because of strong and spatially highly variable interstellar extinction and extreme source crowding, the faint (K>15) stellar population in the Milky Way's nuclear cluster is still…
GRAVITY spectro-interferometric study of the massive multiple stellar system HD 93 206 A
J. Sanchez-Bermudez, A. Alberdi, R. Barba +9
Characterization of the dynamics of massive star systems and the astrophysical properties of the interacting components are a prerequisite for understanding their formation and evo…
IRTF/TEXES Observations of the HII Regions H1 and H2 in the Galactic Centre
Hui Dong, John H. Lacy, Rainer Schodel +6
We present new [Ne II] (12.8 micron) IRTF/TEXES observations of the Galactic Center HII regions H1 and H2, which are at a projected distance of ~11 pc from the center of the Galaxy…
ALMA and VLA observations of emission from the environment of Sgr A*
F. Yusef-Zadeh, R. Schödel, M. Wardle +6
We present 44 and 226 GHz observations of the Galactic center within 20 of Sgr A*. Millimeter continuum emission at 226 GHz is detected from eight stars that have previously bee…
Testing General Relativity with stellar orbits around the supermassive black hole in our Galactic center
A. Hees, T. Do, A. M. Ghez +14
In this Letter, we demonstrate that short-period stars orbiting around the supermassive black hole in our Galactic Center can successfully be used to probe the gravitational theory…
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…
