Time-varying phenomena are one of the most substantial sources of astrophysical information, and their study has led to many fundamental discoveries in modern astronomy. We have developed an automated tool to search for and analyze variable sources in the near-infrared K s band using the data fro...

The 'VISTA Variables in the Vía Láctea eXtended (VVVX)' ESO Public Survey is a nearinfrared photometric sky survey that covers nearly 1700 deg2 towards the Galactic disc and bulge. It is well-suited to search for newopen clusters, hidden behind dust and gas. The pipeline processed and calibrated ...

We present deep near-infrared photometry and spectroscopy of the globular cluster 2MASS-GC 03 projected in the Galactic disc using MMT and Magellan Infrared Spectrograph on the Clay Telescope (Las Campanas Observatory) and VISTA Variables in the Via Lactea Survey data. Most probable cluster membe...

A.[Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC 03]Near-infrared photometry and spectroscopy of the low Galactic latitude globular cluster 2MASS-GC 03

The purpose of this research is to study the connections of the global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Public Survey disk area and their young stellar object (YSO) populations. The analysis is based on the combination o...
