A model for the ongoing subcluster interaction in Centaurus
Felipe S. Lohmann, Magda Arnaboldi, Michael Hilker +10
Intracluster globular clusters (GCs) preserve the hierarchical and chemical history of galaxy cluster assembly. The nearby Centaurus cluster is believed to be undergoing an interac…
SPICY 30021: an embedded bona fide FUor with a mid-infrared precursor
Zhen Guo, Calum Morris, Vitor Fermiano +37
Unstable mass accretion in young stellar objects (YSOs) often leads to observable outbursts, which play a key role in stellar mass assembly during pre-main-sequence evolution. The…
Unresolved triples in the open cluster NGC 2437 (M 46) confirmed by the KMOS VVVX-GalCen Spectroscopic Survey
D. Minniti, T. Palma, C. O. Obasi +31
Recent optical and near-IR photometric databases like Gaia data release 3 (DR3) and the VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey allow the exploration of…
A Newly Discovered VVVX Star Cluster Surfing the Galactic Disk
Elisa R. Garro, José G. Fernández-Trincado, Casmir O. Obasi +15
We report the discovery of Garro 04, a previously unidentified stellar cluster toward the Galactic disc, uncovered as part of the ESO/KMOS VVVX-GalCen Spectroscopic Survey. This ob…
Unresolved triple systems in the aged open cluster Trumpler 19: Discovery, confirmation, and implications
D. Minniti, R. K. Saito, V. D. Ivanov +31
It is difficult to identify unresolved triple and higher-order systems beyond the solar vicinity. Star clusters yield controlled environments with known physical parameters, provid…
A song of interactions and mergers: The case of NGC 4709
S. Federle, M. Gómez, S. Mieske +3
Globular clusters (GCs) are fundamental tools to unveil the interaction and merger history of their host galaxies. Our goal is to perform the photometric analysis of the globular c…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
The turbulent life of NGC 4696 as told by its globular cluster system
S. Federle, M. Gómez, S. Mieske +4
In this work we perform the photometric analysis of the globular cluster system (GCS) of the giant elliptical NGC4696, which is the brightest member of Centaurus, a rich and dynami…
Outbursts of the intermediate-mass black hole HLX-1: a wind instability scenario
Roberto Soria, Aina Musaeva, Kinwah Wu +5
We model the intermediate-mass black hole HLX-1, using the Hubble Space Telescope, XMM-Newton and Swift. We quantify the relative contributions of a bluer component, function of X-…
