Context. Although they are the main constituents of the Galactic disk population, for half of
the open clusters in the Milky Way reported in the literature nothing is known except the raw …

We describe the public ESO near-IR variability survey (VVV) scanning the Milky Way bulge
and an adjacent section of the mid-plane where star formation activity is high. The survey …

Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010.
VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected …

A visual examination of the images from the Galactic Legacy Infrared Mid-Plane Survey
Extraordinaire (GLIMPSE) has revealed 322 partial and closed rings that we propose …

We present results of a study of the galactic open cluster population based on the all-sky
catalogue ASCC-2.5 (I/280A) compiled from Tycho-2, Hipparcos and other catalogues. The …

Young massive stars or clusters are often observed at the peripheries of H ii regions. What
triggers star formation at such locations? Among the scenarios that have been proposed, the …

We report 269 mid-infrared bubbles within 10 of the Galactic center from visual inspection of
the Spitzer GLIMPSE II Legacy Science program images. The surface density of bubbles is …

We used star density maps obtained from the Two-Micron All-Sky Survey (2MASS) to obtain
a sample of star clusters in the entire Galactic Plane with| b|< 20°. A total of 1788 star cluster …

We carried out a survey of infrared star clusters and stellar groups on the 2MASS J, H and K
s all-sky release Atlas in the Northern and Equatorial Milky Way (,). The search in this zone …

We report on the unprecedented red supergiant (RSG) population of a massive young
cluster, located at the base of the Scutum-Crux Galactic arm. We identify candidate cluster …
