First steps of the GTC photometric calibration plan
Large telescopes require a very precise calibration in order to maximize its scientific output. Current catalogues of standard stars are generally too bright...
Formation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...
From blue cloud to red sequence: evidence of morphological transition prior to star formation quenching
We present a study of a sample of 254 clusters from the SDSS-DR7 Yang Catalogue and an auxiliary sample of field galaxies to perform a detailed investigation on...
From 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...
From 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...
Frontier 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...
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...
Further 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...
Galactic 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...
