The globular cluster BH 176 revisited

Globular cluster system and Milky Way properties revisited

Aims. Updated data of the 153 Galactic globular clusters are used to readdress fundamental parameters of the Milky Way, such as the distance of the Sun to the Galactic centre, the bulge and halo structural parameters, and cluster destruction rates. Methods. We build a reduced sample that has been decontaminated of all the clusters younger than 10 Gyr and of those with retrograde orbits and/or e...

Globular Cluster Formation in the Virgo Cluster

Metal-poor globular clusters (MPGCs) are a unique probe of the early universe, in particular the reionization era. A popular hypothesis is that the observed truncation of MPGC formation is due to reionization. Under this hypothesis, constraining the formation epoch of MPGCs provides a complementary constraint on the epoch of reionization. Moreover, as the earliest reionizing sources first forme...

Nearby Spiral Galaxy Globular Cluster Systems II : Globular Cluster

We present new metallicity estimates for globular cluster candidates in the Sd spiral NGC 300, one of the nearest spiral galaxies outside the Local Group. We have obtained optical spectroscopy for 44 Sculptor Group globular cluster candidates with the Boller and Chivens (B&C) spectrograph on the Baade Telescope at Las Campanas Observatory. There are 2 globular clusters in NGC 253 and 14 objects...

The Globular Cluster System of NGC 5846 Revisited : Colours , Sizes and X - Ray Counterparts ⋆

NGC5846 is a giant elliptical galaxy with a previously well studied globular cluster system (GCS), known to have a bimodal colour distribution with a remarkably high red fraction. Here we revisit the central galaxy regions searching for new globular cluster (GC) candidates, and measuring, magnitudes, colours and sizes for them. We also search for their X-ray counterparts. We use archival Hubble...
