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…
A near-infrared stellar atlas of the Galactic plane from the VVVX survey
Javier Alonso-GarcÃa, Maren Hempel, Roberto K. Saito +12
The VISTA Variables in the Via Lactea eXtended (VVVX) ESO public survey observed the Galactic plane and the outer Galactic bulge in the near-infrared to mitigate the effects of ext…
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…
Multi-Wavelength characterization of VVVX open clusters
C. O. Obasi, E. R. Garro, J. G. Fernández-Trincado +4
Context. Large-scale surveys across wavelengths, aided by machine learning, have improved the detection of old open clusters in high-extinction Milky Way regions. Aims. We aim to c…
