The debate about the universality of the stellar initial mass function (IMF) revolves around two competing lines of evidence. While measurements in the Milky...

PublicationThe Unrelaxed Dynamical Structure of the Galaxy Cluster Abell 85
For the first time, we explore the dynamics of the central region of a galaxy cluster within r 500 ∼ 600 h‑1 kpc from its center by combining optical and X-ray...

PublicationThe unusual multi-wavelength SED of two optical dropout galaxies
We have used deep optical, near-IR, and IR observations from VLT, Spitzer, Herschel, and LABOCA in strong lensing clusters to study distant galaxies. In...

PublicationThe Unusual Vertical Mass Distribution of NGC 4013 Seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" H I warp and its "giant" tidal stream. Previous work on this unusual object shows that it...

PublicationThe Updated BaSTI Stellar Evolution Models and Isochrones. I. Solar-scaled Calculations
We present an updated release of the BaSTI (a Bag of Stellar Tracks and Isochrones) stellar model and isochrone library for a solar-scaled heavy element...

PublicationThe Uv Spectral Window: New Means To Constrain The Stellar Populations Of Early-Type Galaxies
We discuss the possibilities of exploiting the UV spectral using the J-PAS survey to disentangle young contributions from apparently old galaxies. We show that...

PublicationThe UV-brightest Lyman continuum emitting star-forming galaxy
We report the discovery of J0121+0025, an extremely luminous and young star-forming galaxy (M UV = -24.11, log[$L_{\rm Ly \alpha } / \rm erg~s^{-1}] = 43.8$) at...

PublicationThe V-band luminosity function of galaxies in A2151
We present a wide field V-band imaging survey of approximately 1 deg2 (~7.2~h-275 Mpc2) in the direction of the nearby cluster of galaxies Abell 2151 (the...

PublicationThe VANDELS ESO public spectroscopic survey
VANDELS is a uniquely deep spectroscopic survey of high-redshift galaxies with the VIMOS spectrograph on ESO's Very Large Telescope (VLT). The survey has...
