PublicaciónFrom kpcs to the central parsec of NGC 1097: feeding star formation and a black hole at the same time
A panchromatic view of the star-forming ring and feeding process in the central kpc of the galaxy NGC 1097 is presented. The assembled IR to UV images at ˜10 pc...

CharlaFrom 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...

PublicaciónFrontier Fields: Combining HST, VLT, and Spitzer data to explore the z ~ 8 Universe behind the lensing cluster MACSJ0416.1-2403
Context. The Hubble Space Telescope (HST) Frontier Fields (HFFs) project started at the end of 2013 with the aim of providing extremely deep images of six...

PublicaciónFueling and Morphology of Central Starbursts
Of the mechanisms proposed to bring gaseous fuel into the central starburst regions of a galaxy, non-axisymmetries in the gravitational potential set up by...

PublicaciónFurther evidence for a time-dependent initial mass function in massive early-type galaxies
Spectroscopic analyses of gravity-sensitive line strengths give growing evidence towards an excess of low-mass stars in massive early-type galaxies (ETGs). Such...

CharlaGalactic Globular Clusters: Why should we care about them?
Galactic globular clusters have always been at the crossroad of several investigations in both Stellar and Galactic Astrophysics. For long time, they have been...

CharlaGamma rays from Young Stellar Objects
In the last years star-forming regions and massive protostars have been suggested to be gamma-ray emitters. Isolated massive protostars present powerful...

PublicaciónGas accretion from the cosmic web in the local Universe
Numerical simulations predict that gas accretion from the cosmic web drives star formation in disks galaxies. The process is important in low mass haloes (<...
