Properties of Galactic Globular Clusters
We have assembled 560 recent measurements from the literature of distances of Galactic globular clusters and found revised distance estimates for 154 of the 157 clusters in the... -
Revised Bologna Catalog of M31 clusters, V.5
The dataset lists all the confirmed globular clusters (GC), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were... -
Globular clusters as gravitational lenses
Based on the SDSS catalog, we have found new close quasar-galaxy pairs. We analyze the radial distribution of quasars from pairs around galaxies of different types. We show that... -
Radial Velocities of Globular Cluster Giants
Velocities are given for 303 giant stars in the globular clusters M3, M13, M15, and M92 from spectra obtained with the 3.5-m WIYN Telescope at the Kitt Peak National Observatory... -
Globular metallicity scale. I.
We have obtained 2640 CCD spectra with resolution ~4{AA} in the region 7250-9000{AA} for 976 stars lying near the red giant branches in color-magnitude diagrams of 52 Galactic... -
NGC 1851 variables light curves
We report VI CCD photometry of the globular cluster cluster NGC 1851. We aim to study the membership of the variable stars detected in the field of the cluster as listed in the... -
Membership catalog for M12 (NGC6218) stars
Using astrometric techniques developed by Anderson et al., we determine proper motions (PMs) in the ~14.60x16.53arcmin^2^ area of the kinematically "thick-disk" globular cluster... -
LAMOST globular clusters in M 31 and M 33
We present a catalog of 908 objects observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in fields in the vicinity of M31 and M33, targeted as... -
UBVRI phot. for galaxies, Gal. GCs & stars
From 1982 January to 1988 October, I used the 76-cm and 91-cm (30-inch and 36-inch) reflectors at McDonald Observatory in West Texas for UBV(RI)c observations of 239 galaxies,... -
Fimbulthul stream candidate stars
Omega Centauri (omega Cen) is the Milky Way's most massive globular cluster, and has long been suspected of being the remnant core of an accreted dwarf galaxy. If this scenario... -
2050 red giants CaII EWs
Globular clusters are some of the oldest bound stellar structures observed in the Universe. They are ubiquitous in large galaxies and are believed to trace intense... -
Na abundances in NGC6752
The asymptotic giant branch (AGB) phase is the final stage of nuclear burning for low-mass stars. Although Milky Way globular clusters are now known to harbour (at least) two... -
Variable stars in the field of NGC 6558
We made a survey of the variable stars in a 13.2x13.2 arcmin^2^ centred on the field of the Galactic bulge cluster NGC 6558. A total of 78 variables were found in the field of... -
HST photometry of NGC 1850
Young star clusters enable us to study the effects of stellar rotation on an ensemble of stars of the same age and across a wide range in stellar mass and are therefore ideal... -
J-PLUS globular cluster cand. around M81
Globular clusters (GCs) are proxies of the formation assemblies of their host galaxies. However, few studies exist targeting GC systems of spiral galaxies up to several... -
Star clusters study in PHANGS-HST galaxies
Using PHANGS-HST NUV-U-B-V-I imaging of 17 nearby spiral galaxies, we study samples of star clusters and stellar associations, visually selected to be bright and relatively... -
GC in 5 nearby spiral galaxies
We here present the luminosity function (LF) of globular clusters (GCs) in five nearby spiral galaxies using the samples of GC candidates selected in Hubble Space Telescope... -
Membership study of 70 stars clusters
Spectroscopy from the final internal data release of the Gaia-ESO Survey (GES) has been combined with Gaia EDR3 to assign membership probabilities to targets observed towards 63... -
Gamma-ray spectra of globular clusters in MW
Millisecond pulsars are very likely the main source of gamma-ray emission from globular clusters. However, the relative contributions of two separate emission processes -... -
Ages and abundances from spectral fitting
The pixel-to-pixel spectral fitting technique is often used in studies of stellar populations. It enables the user to infer several parameters from integrated light spectra such...
