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…
The distribution of stars around the Milky Way's central black hole II: Diffuse light from sub-giants and dwarfs
R. Schödel, E. Gallego-Cano, H. Dong +4
This is the second of three papers that search for the predicted stellar cusp around the Milky Way's central black hole, Sagittarius A*, with new data and methods. We aim to infer…
The distribution of old stars around the Milky Way's central black hole I: Star counts
E. Gallego-Cano, R. Schödel, H. Dong +4
(abridged) In this paper we revisit the problem of inferring the innermost structure of the Milky Way's nuclear star cluster via star counts, to clarify whether it displays a core…
