The early type dwarf galaxy population of the Fornax cluster
... Another mechanism that may in principle cause environmen- tal differences among galaxy populations is re-ionization (e.g. Dekel & Woo 2003; Moore et al. 2006). It is reasonable to as- sume that those galaxy halos that ...

The Formation of Spheroids in Early type Spirals: Clues from Their Globular Clusters
... Object detection was done following the general procedure described in Maybhate et al. (2007). First, we removed the strong and varying galaxy light by applying a circular median filter of radius 15 pixels and dividing ...

Galaxy populations in the Antlia cluster I Photometric properties of early type galaxies
... As said above, for each faint object not detected by SEXTRAC - TOR we have used trimmed and registered images of the same sizes in R and C filters. We estimated the sky level from the statistic provided by IMEXA. After ...

The long bar as seen by the VVV survey I Colour magnitude diagrams
... Using the method described in Sect. 3.3, we can extract the RCGs from a CMD and estimate their distance. This allows us to reconstruct the in-plane 2D distribution of these stars, as can be seen in Fig. 3. Beyond ...

Type II Cepheids: Evidence for Na O anticorrelation for BL Her type stars?
... In the cluster NGC 6218 (M 12), [Fe/H] = − 1.31 ± 0.028 dex, Carretta et al. (2007) found variations in the sodium abundance near the red giant branch (RGB) bump, which the authors believe to be a reflection of different ...
