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…
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…
Chemo-dynamical stratification of the Galactic disc using \emph{Gaia}-ESO open clusters
Casmir O. Obasi, M. Gómez, J. G. Fernández-Trincado +5
Understanding how the Milky Way disc assembled and evolved requires tracing the coupled evolution of stellar chemistry and orbital structure over time. Open clusters, as coeval ste…
Discovery of a low surface brightness galaxy in the Zone of Avoidance using VVVX Deepstack imaging
J. L. Nilo-Castellón, L. Baravalle, D. Minniti +12
We report the discovery of VVVX J080705.96-273823.6, the first low-surface-brightness galaxy candidate identified in the Zone of Avoidance by the VISTA Variables in the Via Lactea…
Consensus based Algorithm for Nonparametric Detection of Star Clusters (CANDiSC)
C O Obasi, J G Fernandez Trincado, M Gomez +14
Context: The VISTA Variables in the Via Lactea (VVV) and its extension (VVVX) are near-infrared surveys mapping the Galactic bulge and adjacent disk. These data have enabled the di…
The VVVX quest for satellites around the Circinus galaxy
L. D. Baravalle, A. L. O'Mill, M. V. Alonso +10
The Circinus galaxy is the nearest type-2 Seyfert galaxy, which is at a distance of 4.2 Mpc. Its environment is challenging to explore because it is located at low Galactic latitud…
Faint galaxies in the Zone of Avoidance revealed by JWST/NIRCam
J. L. Nilo-Castellón, M. V. Alonso, L. Baravalle +12
The Zone of Avoidance (ZoA) remains one of the last frontiers in constructing a comprehensive three-dimensional map of the Universe. Galactic extinction, stellar crowding, and conf…
High energy gamma-ray sources in the VVV survey - III. Spectroscopic confirmation of an AGN at low Galactic latitudes
Eduardo O. Schmidt, Laura D. Baravalle, Ana Pichel +9
We aim to spectroscopically confirm the nature of VVV-J181258.71-314346.7, a candidate counterpart to the unassociated gamma-ray source 4FGLJ1812.8-3144. This object was selected b…
The VVV near-IR galaxy catalogue of the southern Galactic disc
M. V. Alonso, L. D. Baravalle, J. L. Nilo Castellón +16
The distribution of galaxies in the Zone of Avoidance (ZoA) is incomplete due to the presence of our own Galaxy. Our research focused on the identification and characterisation of…
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…
Galaxies in the zone of avoidance: Misclassifications using machine learning tools
P. Marchant Cortés, J. L. Nilo Castellón, M. V. Alonso +10
Automated methods for classifying extragalactic objects in large surveys offer significant advantages compared to manual approaches in terms of efficiency and consistency. However,…
Searching for globular clusters in the inner halo of the Circinus galaxy
C. O. Obasi, M. Gomez, D. Minniti +3
In this study, we search for Globular Clusters (GCs) in the inner halo of the Circinus galaxy using a combination of observational data. Our dataset includes observations from the…
High energy gamma-ray sources in the VVV survey -- II. The AGN counterparts
Laura G. Donoso, Ana Pichel, Laura D. Baravalle +9
We identified Active Galactic Nuclei (AGN) candidates as counterparts to unidentified gamma-ray sources (UGS) from the Fermi-LAT Fourth Source Catalogue at lower Galactic latitudes…
The VVV Near-IR Galaxy Catalogue beyond the Galactic disk
Laura D. Baravalle, M. Victoria Alonso, Dante Minniti +7
Knowledge about the large-scale distribution of galaxies is far from complete in the Zone of Avoidance, which is mostly due to high interstellar extinction and to source confusion…
The star cluster system of the 3 Gyr old merger remnant NGC 1316: Clues from optical and near-infrared photometry
Paul Goudfrooij, M. Victoria Alonso, Claudia Maraston +1
The giant merger remnant galaxy NGC 1316 (Fornax A) is an ideal probe for studying the long-term effects of a past major merger on star cluster systems, given its spectroscopically…
