The age–metallicity relationship in the Fornax spheroidal dwarf galaxy [PDF]
, 2014 We produce a comprehensive field star age–metallicity relationship (AMR) from the earliest epoch until ∼1 Gyr ago for three fields in the Fornax dwarf spheroidal galaxy by using VI photometric data obtained with FORS1 at the VLT.

Lithium in the Hyades L5 brown dwarf 2MASS J04183483+2131275 [PDF]
, 2018 Aims. From the luminosity, effective temperature and age of the Hyades brown dwarf 2MASS J04183483+2131275 (2M0418), substellar evolutionary models predict a mass in the range 39−55 Jupiter masses (MJup) which is insufficient to produce any substantial ...

On the Anticorrelation Between Galaxy Light Concentration and X-ray-to-Optical Flux Ratio [PDF]
, 2009 Active Galactic Nuclei (AGN) play an important role in many aspects of the modern cosmology, and of particular interest is the issue of the interplay between AGN and their host galaxy. Using X-ray and optical data sets, we have explored the properties of
