We present deep VI-band photometry of the globular cluster M54, a nearby field in the
Sagittarius dwarf galaxy, and a control field. The color-magnitude diagrams reach well …

We examine the correlation between globular cluster (GC) color and magnitude using HST
ACS imaging for a sample of 79 early-type galaxies (-21.7< MB<-15.2 mag) with accurate …

Context. Metal-poor globular clusters in the bulge are important tracers of early chemical
evolution. HP-1 is among the six metal-poor clusters within 5° of the Galactic center, and …

We present VI color-magnitude diagrams (CMDs) of the globular cluster NGC 6558 and its
surrounding field, obtaining cluster parameters. The cluster has a blue extended horizontal …

Hubble Space Telescope observations in the F555W and F814W bands are presented of
the bulge globular cluster Terzan 1. This highly obscured cluster has the smallest projected …

This paper presents integrated spectra in the range 6700-9500 for 20 Galactic globular
clusters (and candidates) in the bulge and 5 others projected on the Galactic disk (and) …

The integrated spectral properties in the range 3600–6700 Å of the candidate old clusters
NGC 1928 and 1939 in the LMC bar are compared with those of old-and intermediate-age …

The combination of ever more precise radio timing data and serendipitous {\it HST} data has
confirmed that the outer companion to PSR B1620 $-$26 is a planet. Here we summarize …

Historically, it has been assumed that globular and open clusters never interact. However,
recent evidence suggests that: globular clusters passing through the disk may be able to …

We plot the globular clusters of the Fornax galaxy and those associated with the Sagittarius
dwarf spheroidal galaxy in the horizontal-branch type versus metallicity diagram. The …
