The 31 brightest galaxies (mB ≤ 15 mag) inside the virial radius of the Fornax cluster were observed from the centres to the outskirts with the Multi Unit...

Context. The Southern Photometric Local Universe Survey (S-PLUS) is a project to map ~9300 sq deg of the sky using twelve bands (seven narrow and five...

In this article we demonstrate that PKS J1037-2705 has a weak accretion flow luminosity, well below the Seyfert 1/QSO dividing line, weak broad emission lines...

The fundamental metallicity relation (FMR) states that galaxies of the same stellar mass but larger star formation rate (SFR) tend to have smaller gas-phase...

Studying three samples of early-type galaxies, which include approximately 8800 galaxies and cover a relatively ample magnitude range ( ~ 5.5mag), we find that...

Aims: Near-IR photometry of dwarf irregular galaxies (dIs) has been acquired to expand the sample of objects suitable for investigating the fundamental plane...

We present a study focusing on the nature of compact groups through the study of their elliptical galaxies. We determine velocity dispersions (σ) for 18 bright...

We collected photometrical and dynamical data for 73 low red-shift (z

Context. The Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending...
