Massive relic galaxies formed the bulk of their stellar component before z ˜ 2 and have remained unaltered since then. Therefore, they represent a unique...

The initial mass function (IMF) of early-type galaxies (ETGs) has been found to feature systematic variations by both dynamical and spectroscopic studies. In...

We present a new approach to studying the initial mass function (IMF) in external galaxies based on quasar microlensing observations. We use measurements of...

Context: The initial-final mass relationship of white dwarfs, which is poorly constrained, is of paramount importance for different aspects of modern...

Recent data from the VVV survey have strengthened evidence for a structural change in the Galactic bulge inward of |l|

We infer the central mass distributions within 0.4-1.2 disc scalelengths of 18 late-type spiral galaxies using two different dynamical modelling approaches -...

We revise the explanation for the ``expanding H II regions ring'' of NGC 4736. From the analysis of long-slit spectra, we identify structures within the...

We present a comprehensive multiwavelength photometric analysis of the innermost (˜3 × 3 kpc2) 110 globular clusters (GCs) of M87. Their spectral energy...
