GALACTICNUCLEUS: A high angular resolution imaging survey of the Galactic Centre. I. Methodology, performance, and near-infrared extinction towards the Galactic Centre
F. Nogueras-Lara, A. T. Gallego-Calvente, H. Dong +8
The Galactic Centre is of fundamental astrophysical interest, but existing near-infrared surveys fall short to cover it adequately. We introduce the GALACTICNUCLEUS survey, a $JHK_…
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…
Near-Infrared Variability Study of the Central 2.3 arcmin x 2.3 arcmin of the Galactic Centre I. Catalog of Variable Sources
Hui Dong, Rainer Schodel, Benjamin F. Williams +7
We used four-year baseline HST/WFC3 IR observations of the Galactic Centre in the F153M band (1.53 micron) to identify variable stars in the central ~2.3'x2.3' field. We classified…
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 the gravitational theory with short-period stars around our Galactic Center
A. Hees, A. M. Ghez, T. Do +19
Motion of short-period stars orbiting the supermassive black hole in our Galactic Center has been monitored for more than 20 years. These observations are currently offering a new…
