Globular cluster systems of 17 elliptical galaxies have been studied in the Coma Cluster of galaxies. Surface-brightness fluctuations have been used to...

We analyse the globular cluster (GC) systems of a sample of 15 massive, compact early-type galaxies (ETGs), 13 of which have already been identified as good...

Context: .Shells in Elliptical Galaxies are faint, sharp-edged features, believed to provide evidence of a recent (˜ 0.5 - 2 × 109 years ago) merger event. We...

As ancient star clusters, globular clusters (GCs) are regarded as powerful tracers of galaxy evolution and assembly. Due to their brightness and compact sizes...

We have analyzed archival Hubble Space Telescope Advanced Camera for Surveys images in g and z of the globular cluster (GC) systems of 53 ellipticals in the...

We present an analysis of archival HST/ACS imaging in the F475W (g 475), F606W (V 606), and F814W (I 814) bands of the globular cluster (GC) system of a large...

We present U and B galaxy differential number counts from a field of ~900 arcmin2, based on GOYA Survey imaging of the HST Groth-Westphal strip. Source...

We present U and B galaxy number counts from a field that comprises a 0.29 square degrees area of sky, and which covers the Groth-Westphal Strip (Groth et al...

We present the results of our search near the end of the Reionization Epoch for faint galaxies. This has been done using very deep OSIRIS images obtained at the...
