Astrophysics and Space Science, 2012, Volume : 341, Numéro : 1
The surface brightness fluctuations (SBF) method measures the variance in a galaxy's light distribution arising from fluctuations in the numbers and...
We combined new near-infrared VLT/HAWK-I data of the globular clusters (GCs) in the isolated edge-on S0 galaxy NGC 3115 with optical and spectroscopic ones...
The Astrophysical Journal, 2013, Volume : 769, Numéro : 2
We study the azimuthal distribution of globular clusters (GCs) in early-type galaxies and compare them to their host galaxies using data from the ACS Virgo...

Aims. The distance of NGC 1316, the brightest galaxy in the Fornax cluster, provides an interesting test for the cosmological distance scale. First, because...
The Astrophysical Journal, 2013, Volume : 768, Numéro : 2
Color distributions of globular clusters (GCs) in most massive galaxies are bimodal. Assuming linear color-to-metallicity conversions, bimodality is viewed as...
The Astrophysical Journal, 2012, Volume : 746, Numéro : 1
We combine new Wide Field Camera 3 IR Channel (WFC3/IR) F160W (H 160) imaging data for NGC1399, the central galaxy in the Fornax cluster, with archival F475W...
Monthly Notices of the Royal Astronomical Society, 2012, Volume : 422, Numéro : 4
Deep images of 10 early-type galaxies in low-density environments have been obtained with the Advanced Camera for Surveys (ACS) aboard the Hubble Space...
The Advanced Camera for Surveys (ACS) Fornax Cluster Survey is a Hubble Space Telescope program to image 43 early-type galaxies in the Fornax cluster, using...
The Astrophysical Journal, 2013, Volume : 775, Numéro : 1
We study the rich globular cluster (GC) system in the center of the massive cluster of galaxies Abell 1689 (z = 0.18), one of the most powerful gravitational...
Monthly Notices of the Royal Astronomical Society, 2013, Volume : 437, Numéro : 2
We use our integrated Sloan Digital Sky Survey (SDSS) photometry for 96 globular clusters in g and z, as well as r and i photometry for a subset of 56...
