... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

Target names are used to provide unique designations for the targets that will be used throughout the proposal. These names will generally also be used in Phase II, and ultimately to designate targets in the HST data archive. ... This facility will be most useful if consistent naming conventions are used. ... If a target is not contained in these catalogs, other catalog designations may be used (e.g., 4U X-ray catalog designation, Villanova white-dwarf catalog number, etc.) ... Target Type . ...

... Science . ... Science Users Information > Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: Studying the first galaxy clusters with ALMA . ... ALMA will provide a major leap forward in our capabilities of studying the high-redshift universe, especially the first galaxies. ... These first galaxies are also found to cluster relatively strongly, and are expected to form proto-clusters, later growing to be the fully-formed galaxy clusters we see in the local Universe....

... Our Milky Way galaxy is host to a number of companions. These companions are gravitationally bound to the Milky Way and are stellar systems in their own right. They include a population of about 150 globular clusters (GCs) and some 30 dwarf satellite galaxies (DSGs). ... These DSGs are more extended and diffuse compared to GCs. In fact the larger satellites of the Milky Way (and other galaxies, for that matter) host their own small systems of GCs. ...
