With the aim of detecting cosmological gas accretion onto galaxies of the local Universe, we examined the Ha emission in the halo of the 164 galaxies in the...

TalkFeII emission in active galactic nuclei: results from NIR Spectroscopy
FeII comprises up to one third of the line emission in AGNs. For that reason it is an important coolant that needs to be taken into accountto fully understand...

TalkFifty years of secular evolution in galaxies: where do we stand?
In this talk I will present my view on what we know and what we don't know about the so-called secular evolution processes in galaxies. I will focus on the...

TalkFormation and evolution of double-barred galaxies
The general picture of galaxy formation and evolution includes bars as the main drivers of the internal secular processes affecting the lifetime of disc...

TalkFrom Cosmology to Galaxies and Back Again
The evidence for the existence of dark energy is conclusive, but its nature remains one of the most puzzling mysteries in all of physics. Astronomical surveys...

TalkFrom the blue cloud to the red sequence (and over the green valley): investigating the evolution of galaxies over cosmological timescales
In the local universe, galaxies fall into one of two populations: a star-forming blue cloud and a red sequence lacking star formation. At redshift z ~ 1.5...

TalkGalactic archeology of thick discs: excavating ESO 533-4 with VIMOS and ESO 243-49 with MUSE
The disc of galaxies is made of the superposition of a thin and a thick disc. Thick discs are seen in edge-on galaxies as excesses of light a few thin disc...

TalkGalactic Dynamics to Explain Outer Disc Features in Spiral Galaxies
Milky Way and most spiral galaxies present some features in the outer part of its disk such as S-warping or U-warping, flaring, lopsidedness, truncation/non...

TalkGalactic Palaeontology
I will talk about how resolved stellar populations in the nearby Local Group dwarf galaxies have been used to study the detailed chemical, kinematic and star...
