New compact star cluster candidates in the Galactic plane. (2017)

Keywords : Galaxy evolution - Galaxy: general - open clusters and associations: general - Galaxy: structure - galaxies: star clusters: general

Abstract:The sample of known star clusters, the fundamental building blocks of galaxies, in the Milky Way is still extremely incomplete for objects beyond a distance of 1-2kpc. Many of the more distant and young clusters are compact and hidden behind large amounts of extinction. We thus utilized the deep high-resolution near-infrared surveys UGPS and VVV to uncover so far unknown compact clusters and to analyse their properties. Images of all objects in the area covered by these two surveys, which are listed as galaxy in SIMBAD, have been inspected and 125 so far unknown stellar clusters and candidate clusters have been identified. Based on the frequent associations with star formation indicators (nebulosities, IRAS sources, HII regions, masers) we find ...(more)

Monthly Notices policies
In order to identify potentially undetected star cluster (candidates) in the Galactic plane, we manually inspected images from the UGPS and VVV surveys for all objects classified as 'Galaxy' in SIMBAD to identify misclassified star clusters. A total of 4387 objects were initially selected and JHK images for 3409 of those were available and investigated in detail in an area of 2350 deg^2^ over both surveys. In total, we have identified 77 new clusters, 53 of which are not included in the list of Lucas et al. (in preparation). All the determined properties are listed in Table A1.
