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…
